Could have faulty or clogged fuel injectors,could have bad ignition coils bad spark plugs wires or spark plugs, spark plugs probably getting oil on them due to leaking oil leaking by valve cover circular seals around spark plugs or you have a intake manifold leak at cylinder 1 and 2

    is it possible that i may have to replace the upper or lower intake gaskets

  • Jonah Oneal Oct 31, 2012

    check fuel injectors and ignition coils using volt ohm tell you if you have open in fuel injector windings or ignition coils winding if injector or coil or coils has a open winding volt ohm meter will give you a zero reading that mean bad.use a engine vacuum gauge look at vacuum gauge while engine running the vacuum gauge needle will steady drop if you have bad valves or could just need to adjust valve lash intake valve clearance is 0.006 and the exhaust valve clearance is 0.012 inch

This could be an ignition coil, spark plug, fuel injector or mechanical problem. You will need to isolate the issues and proceed accordingly. I would do some swapping arround. Swap the spark plugs 1 and 2 with m# and four and see if the misfire follows if it does you need plugs do the same with the coils again if the probles switches cylinders replace coils. if not then you may have to llok at injectors, compression and so on but I would try swapping things first

    i recently had all the sparkplugs and wires replaced....also the egr valve...the strange thing is once its been ran for 30 minutes or so the problem goes away completely, until you let it sit for a couple of hours....should i try changing the injectors of the misfiring cylinders? and if so what should i know about replacing them,,,,

  • Hector L. Morales Oct 29, 2012

    Not the path I would go. Just based on the information I am getting. Not that it isn't possible. Was the problem there prior to the t/u? Or did it begin after?

  • larry cook Oct 30, 2012

    the problem was there was before the tune up.....could it be the upper or lower intake gaskets?...is there away u can tell if the coils are bad, gonna try that next....thanks for your help, im not the worlds best mechanic

  • Hector L. Morales Oct 31, 2012

    Here is what's throwing me off; you have an 01 tribute v6, right? It is my understanding that this is a coil over plug engine yet you said the plugs and wires were replaced. Lets clear the misunderstanding up. If it is a v6 and has coil over plug take coils from 1 & 2 and move them to the front to 4 & 5. If the misfires move from 1 & 2 to 4 & 5 replace the coil. To move 1 & 2 to the front the intake will need to be unbolted and moved just enough to create clearance and remove the coils. If my assumption is incorrect please let me know. Can a leaking intake gasket cause it yes it can. There are many factors hopefully we can narrow them down.

  • Hector L. Morales Oct 31, 2012

    Possible causes; Faulty spark plug, Faulty ignition coil, Ignition coil harness is open or shorted, Ignition coil poor electrical connection, Clogged or faulty fuel injector, Injector harness is open or shorted, Injector poor electrical connection, Improper spark plug/gap, cylinder #1 compression, Intake air leak. Same would apply to cylinder #2.

    If I had to bet, I would bet on the ignition coil. They are Ford coils and really not very good. I think I paid about $60 a piece at Pep Boys for them.

SOURCE: cylinder not firing

Have you verified that you are getting spark at the plug when the engine turns over? To do this you can remove the spark plug and insert it into the end of the plug wire. Set the electrode against something metal on the engine. Crank the engine and watch for spark. If you get spark, then you can start thinking about timing, cylinder, fuel problems. If you don't get spark, think about distributor cap/rotor or wire problem.

SOURCE: The engine on my sons 91 Mazda Miata is running

You have done a great test but If I assk you to do a swap of the Ist cylinder plug and injector with one from the 3rd , we can come to a conclusion before we can change the full set of plugs and injectors for a good performance.( only if the mileage is time enough to do the change)
If you have confirmed with the spark and the fuel ( hope the fuel pressure is good and the pump calibrated , even though this is not relevant) please also check the wires to the first plug and the fuel line to the first injector.
I hope there is no issues in the pump finally for not releasing enough fuel to the first.( Check for presence of fuel pressure in this line)
I am sure you are confident enough to get to the fault .
Hope you credit me if this helps a bit. Good day

The injectors are weak/faulty.All the injectors needs to be replaced.This will solve the problem.The misfire is caused by faulty injectors. front plugs (cylinders 2,4,6) and rear plugs (1,3,5) .Replace all the cylinders. This cylinders gets covered by carbon layer and this causes the injectors to stop working.This carbon gets build up on the injectors due to faulty o2 sensor.So check if there is carbon build up on injectors replace all o2 sensor then check.If still the misfiring is there then replace all the injector cylinders this will clear the problem.

2006 ford five hundred - engine code P0301. When first starts, no issues, but then idle gets rough and car loses power. Miles from home with no tools but willing to do whatever.


P0301 cylinder # 1 misfire !
P030x - Cylinder x Misfire Detected Description: NOTE: x represents cylinder number 1 through 9.
The misfire detection monitor is designed to monitor engine misfire and identify the specific cylinder in which the misfire has occurred. Misfire is defined as lack of combustion in a cylinder due to absence of spark, poor fuel metering, poor compression, or any other cause. Possible Causes:
  • Ignition system
  • Fuel injectors
  • Running out of fuel
  • EVAP canister purge valve
  • Fuel pressure
  • Evaporative emission system
  • EGR system
  • Base engine
Diagnostic Aids: The malfunction indicator lamp (MIL) blinks once per second when a misfire severe enough to cause catalyst damage is detected. If the MIL is on steady state due to a misfire, this indicates the threshold for emissions was exceeded and caused the vehicle to fail an inspection and maintenance tailpipe test.

I have a 95 camaro with a 3.8l. It had a #1 cylinder missfire code, I found out it had a bad fuel injuector so i replaced it. Now, it's showing a random misfire code. What could cause this change


An intake vacuum leak can cause this as well as other issues, read about it below.
Check Engine Light On, P0300 Random Misfire Code A random misfire means your engine is misfiring, but that the problem is not isolated to one or two cylinders. It is jumping around in a random way from one cylinder to another. A random misfire code usually means the air/fuel mixture is running lean. But the cause might be anything from a hard-to-find vacuum leak to dirty fuel injectors, low fuel pressure, a weak ignition coil, bad plug wires, or compression problems. Even a dirty MAF sensor can cause a lean code and/or misfire to occur. The engine may be stalling because it isn't getting enough throttle opening. The cause is often a problem in the idle air control system. The first thing to check is the intake vacuum with a vacuum gauge. On most vehicles a normal reading is 17 to 21 inches Hg. If the needle is lower, is jumping up and down or steadily dropping, you have a vacuum problem. Look for possible vacuum leaks by checking vacuum hose connections, the throttle body and manifold, and PVC valve and plumbing. An EGR valve that is leaking can also act like a vacuum leak and cause a random misfire. The next thing you should check is the fuel pressure with a gauge. If it is not within specifications (refer to a service manual for specifics because fuel pressure is critical for proper engine performance), the problem may be a weak fuel pump, low voltage to the pump (check the relay and wiring), or obstructions in the fuel line (like a plugged filter). A bad fuel pressure relay can also leak pressure and prevent an otherwise good fuel pump from delivering full pressure to the injectors. Dirty injectors can also restrict fuel delivery and cause a lean fuel condition. Many regular grades of gasoline do not contain adequate levels of detergent to keep the injectors clean. Frequent short trip driving accelerates the buildup of injector deposits. Cleaning the injectors with a good quality fuel tank additive (or having them professionally cleaned) can solve this problem. Look at short term fuel trim (STFT) and long term fuel trim (LTFT) with your AutoTap Express DIY. If the numbers are high, it tells you the engine is running lean

I am having ongoing problems with the truck miss firing and rough running. Timing is ok, replaced cap and rotor,coil. It still starts rough,idles rough and misses when at cruising speed,although it seems...


Misfire is a common driveability problem that may or may not be easy to diagnose, depending on the cause. A misfiring cylinder in a four-cylinder engine is, pardon the pun, hard to miss. The loss of 25% of the engine's power output is the equivalent of a horse trying to run on three legs. The engine may shake so badly at idle that it causes vibrations that can be felt in the steering wheel and throughout the vehicle. The engine also may be hard to start and may even stall at idle, depending on the accessory load (air conditioning, headlights and electric rear defroster, for example).

When misfire occurs, performance suffers along with fuel economy, emissions and idle quality. And, when a misfiring vehicle is subjected to an emissions test, it will usually fail because of the unusually high levels of hydrocarbons (HC) in the exhaust.

What causes a cylinder to misfire? Basically, it's one of three things: loss of spark; the air/fuel mixture is too far out of balance to ignite; or loss of compression. Loss of spark includes anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. Causes include worn, fouled or damaged spark plugs, bad spark plug wires or even a cracked distributor cap. A weak coil or excessive rotor gas inside a distributor would affect all cylinders, not just a single cylinder.

"Lean misfire" can occur when the air/fuel mixture is too lean (not enough gasoline in the mixture) to burn. This can be caused by a dirty, clogged or inoperative fuel injector; air leaks; or low fuel pressure because of a weak pump, restricted filter or leaky pressure regulator. Low fuel pressure would affect all cylinders rather than an individual cylinder, as would most air leaks. A leaky EGR valve can also have the same effect as an air leak.

Loss of compression means the cylinder loses most of its air/fuel mixture before it can be ignited. The most likely causes here are a leaky (burned) exhaust valve or a blown head gasket. If two adjacent cylinders are misfiring, it's likely the head gasket between them has failed. Also, if an engine is overheating or losing coolant, it's likely the head gasket is the culprit.

Intermittent misfires are the worst kind to diagnose because the misfire comes and goes depending on engine load or operating conditions. They seem to occur for no apparent reason. The engine may only misfire and run rough when cold but then smooth out as it warms up. Or, it may start and idle fine but then misfire or hesitate when it comes under load. Also, it may run fine most of the time but suddenly misfire or cut out for no apparent reason. Intermittent misfires can be a real challenge to diagnose, so let's start with a steady misfire in one cylinder before moving on to intermittent misfires.

Hope this help.

i have a 2001 chevy z-71 5.3L. I keep getting a random/multiple misfire code for cylinder 1 . I have replaced plugs, wires, coil pack(only on #1 cylinder)., and fuel pump. I still keep getting the cylinder 1 misfire code. I put truck on a scanner and watched the cylinders. # 1 misfires at idle but quickly stops misfiring at around 1000 rpms. you can here the engine miss at idle but truck runs great on road . anyone else ever had this problem?
