SOURCE: #4 CYLINDER MISFIRE

Hi the most likely fault would probably be head gasket, it maywell show no other signs of fault as it can blow into next cylinder.
Have a compression test carryed out and all 8 cylinders should be within 10% of each other.

SOURCE: Engine misfire...

First off what you want to do is see if the coil is keeping fire to the cylinders. If so is the fire blue or redish/orange. If it is blue then its not a firing issue. If it is red then you probally need a new coil. Now if you chose option A then check the spark plugs and make sure they aren't fouled out. The way to determin this is that they will be black and smell like gas really bad.If not then check the spark plug wires and make sure they are not ripped, broken, cracked, or show any signs of failure, If not then make sure it is getting plenty of gas. If not then it is either the fuel pump or the fuel filter. If it is a fuel injected engine then make sure the injectors are all working properly. To do this you will probally have to bring it into a shop and have them check. If it is a carberated engine then manually chock the carberatur by holding the top flutter valve closed for a second or two. If the flutter valve gets covered in gas real quickly (in less than 2 seconds) then it should not be a problem with the carburator. If you are still haveing problems with it after checking all of this then give me a shout back and i will see what i can do.

SOURCE: one cylinder misfiring. checked injectors and tappet clearance both okay. Suspect poor compression on cylinder number one. Defender 110 tdi

I take it you have also checked plug and wire. If so could have carbon build up causing valve sticking or camshaft rolled lobe or bad lifter, bent pushrod. This about covers all other possibilitys

I have a 2007 ford taurus with p0300-p0303, p0306, p0316, p2195 and p2196. engine doesnt start anymore but battery is fine.


The old give me money for nothing statement from a mechanic instead of knowing how to fix it.
code p0300 refers to random/ multiple cylinder/s misfire detected===causes--spark plug/s---HT lead/s---injector/s---ignition coil/s--low compression--wiring
code po303 refers to cylinder 3 misfire detected--- engine mechanical fault---wiring---ignition/ fuel system---injector --ECT/MAF sensor --- ECM
code p0306 refers to cylinder 6 misfire detected===causes --engine mechanical fault---wiring---ignition / fuel system---injector ---ECT/MAF sensor---ECM
code po316 refers to misfire detected during start up--first 1000 revs==causes--engine mechanical fault---wiring---ignition /fuel system---injector
code po2195 refers to heated oxygen sensor (HO2S) 1 bank 1 signal stuck lean===cayses ---HO2S---fuel pressure---injectors---intake leak
it also refers to O2S sensor 1 bank 1 same causes and also refers to HO2S 1 bank 1 implausible signal===causes --- short to positive---short to ground---Ho2S ---ECM
code po2196 refers to the same items as 2195 . some causes are also air intake restricted
Have a compression test done some where else and it will indicate the condition of the motor. The rest is sensors and wiring problems.

2003 grand marquis with misfire code p0316


The first problem you have is assuming that the ignition coil is the only thing that can cause a misfire.

Diagnostic Test Code (DTC) P0316 is a "continuous memory only" code that indicates that there is a fault causing a misfire during the first 1000 revolutions of the crankshaft immediately after engine start-up. This should be accompanied by the regular cylinder misfire monitors (Codes P0301 through P0310) unless the misfire does not continue long enough for the regular misfire monitors to determine which cylinder is misfiring.

In order to determine what is actually causing the problem, you must have access to a scan tool that can perform Key On Engine Off (KOEO) fault testing and Key On Engine Running (KOER) fault testing as well as interfacing with the onboard engine computer to read live data and perform system tests.

Please note that generic OBD code readers DO NOT have the capabilities to do what you need to diagnose this problem. You will most likely get additional DTCs that can help lead you to find the source of the problem when KOEO and KOER tests are run. Generic OBD code readers can access only continuous memory DTCs.

Possibilities/conditions/systems that can cause this code are:
>Camshaft Position Sensor
>Low fuel: less than 1/8 tank
>Stuck open EGR Valve
>Blocked EGR passages
>Ignition system
>Fuel Injectors
>Fuel injector control circuits
>Running out of fuel
>EVAP canister purge valve
>Fuel Pressure
>Evaporative emissions system
>Base engine (mechanical) problems

CHUGGING ALONG WITH FLASHING CHECK ENGINE LIGHT....???? 2002 FORD WINDSTAR WHERE TO BEGIN


A flashing Check Engine light means you have a ignition Misfire, start by replacing the spark plugs and spark plug wires, one or more is defective. If you have a electronic engine control fault code reader the cylinder or cylinders that are misfiring will set a fault code, the codes are P0300-P0306, the last number being the number of the cylinder ( cylinders 1-6) the computer has detected a misfire in.

CODES-PO301-PO303-PO316- CHANGED PLUGS & WIRES. STILL MISS ON START UP, GOES AWAY MOST OF THE TIME ABOVE 1000 R.P.M


P0301 - Cylinder 1 Misfire Detected.

Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak

Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1

P0303 - Cylinder 3 Misfire Detected.
Follow info from P0301.

P0316 - Misfire Occurred In The First 1,000 Engine Revolutions.

Causes:
- Damaged CKP sensor.
- Ignition System.
- Fuel Injectors
- Running out of fuel
- Fuel Quality
- Base engine
- Damaged Powertrain Control Module

Solutions:
Usually the P0316 is combine with a P03XX codes. The P03XX code indicates in which cylinder the misfire occurred.

WHAT IS THE CAUSE OF THE PO301 CODE?


The error code p0301 ,This code is related to misfire.The cylinder is misfiring. p0301 this is the indication of cylinder number 1 ,that is misfiring.If the code comes up as p0300 this is the indication of random misfire from all the cylinders.But in your case its indicating p0301 this is indication of cylinder 1 misfire.Check cylinder 1 and replace the faulty cylinder 1 to clear the fault.The spark plugs and the wires connecting to spark plugs also needs to be checked. Keep updated with any more query.Thanks.

Used seafoam in oil engine misfiring


determine when it misfires, and isolate cylinders. a poormans method is use an infrared temperature gun (one with high range, 700 degrees or more is preferable) and with engine held at rev(say 2500) point at each exhaust port 1 by 1, misfiring holes have colder exhaust than firing holes.
If the misfire is momentary or intermittant, or caused by defective cam or crank sensors, you should see professional help...those problems require more advanced equipment to get the 1st time, unless you dont mind lobbing expensive parts randomly till you get lucky

Fault code I believe is p0300


P0300 is a misfire that the engine computer hasn't or can't pinpoint to a specific cylinder yet
