SOURCE: Check engine light on

There are three kinds of gasoline engine misfire scenarios, first there is the "under load" misfire and there is the "at engine idle" misfire, and finally there is misfire continuously. All engine misfires exist because one of three things has occurred. First, a cylinder has lost compression, a cylinder needs a certain amount of compression to operate correctly. Second, the ignition system has failed or is failing intermittently, spark is needed at the time of compression to ignite the fuel air mixture. Third, the fuel air mixture is incorrect, proper mixture is needed for the ignition system to ignite fuel properly. If any of these conditions occur in the engine, the engine will misfire.
1. Low or no compression can be caused by

a. burned or leaking intake or exhaust valves
b. worn or broken piston or piston rings
c. worn out camshaft
d. wrong weight motor oil was installed holding the cam followers from adjusting
e. broken valve spring
f. failed head gasket.
2. Ignition system has failed or is failing
a. spark plug has fouled or is worn out
b. ignition coil
has failed
c. spark plug wires have shorted
e. engine control module coil driver has failed
3. Fuel/Air Mixture is incorrect
a. vacuum leak at the intake manifold
b. fuel injector has failed
c. EGR valve is stuck open
d. mass air flow sensor has failed
e. oxygen sensor has failed
f. air intake boot is cracked

common problems:
1. fuel injector has failed or is failing
2. spark plug wire has shorted
3. spark plug is worn out or is cracked
4. ignition coil has failed is failing

Testing a coil on the car is pretty easy. No special tools are required. Just remember to be careful, the amount of electricity generated by your ignition system can be dangerous. If your coil is already off the car, or if you would like a more specific data-driven test, you can bench test your coil. To set up the test, remove one spark plug wire from its plug, then remove the spark plug using a spark plug socket. Next put the spark plug back into the spark plug wire. Be careful not to let anything drop into the empty spark plug hole -- very bad.

SOURCE: Check engine light comes on. p0171 and p0351 codes found

From Lusty Kid:

I know the economy is bad, but change all of the plugs. Check your PCV Valve hose, 150 rottens them out allowing air to be sucked in, thus all kinds of codes.

Depending on mileage. Dismount the EGR valve and clean passages. If you are really good dismount the throtle position sensor body and clean out passages with Choke Cleaner., dismount where the EGR valves connects to the engine, clean out passages. Also check the hose thats behind this mounting to ensure is not clogged. If clogged clean it out. If not replace it. Is about 1.5 ft. long, connects to the PCV Valve Hose.

When is the last time you change your harness. Can't remember??? Replace it. Good Luck

SOURCE: 2002 kia sedona 3.5l has rough idle replaced plugs wires and coil

this vehicle has coil packs for the ignition correct? have you ran the engine at night with all surrounding lights outs so its really dark. spray a mist of water on the coil packs and spark plug wires to see if you have spark/voltage leaks jumping out from them. sometimes the tiny sparks will be so fine and skinny you can barely see them so it needs to be dark. hope this helps your trouble shooting. a coil pack could have such a fine crack for the voltage to leak from that you cant see it.

SOURCE: 1999 gs300 shows code p1349 and the engine runs

Its a Oil Control Valve most likely. Get the valve. Its like 100 from Lexus. Mine did the exact same thing with that code. GS300

1998 bmw 540i having a misfire on cylinder 5 changed the plugs and coil packs. It ran fine for a couple days, then it began again, giving me a check engine, and it's idling rough at low rpms.


Is the same cylinder causing the problem? If so take a close look at the spark plug for fuel fouling. The cylinder may be over fueled causing plug fouling. You may also have a bad coil or defective spark plug. Try swapping coil and plug with one from adjacent cylinder to see if misfire changes to that cylinder

Cylinder 3 and 4 misfire


Could be a bad cam or crank sensor. But before you go to electronics, ck the plugs, wires & coil or coils (whichever coil system you have) Start with the plugs

I have a 97 dodge caravan 2.4L dohc. I started with an engine code of p0303 and p0304. The vehicle has a rough idle and has difficulty accelerating from idle to 35mph. I've run several tests; 1, pulled all...


DTC P0303: Cylinder 3 Misfire Detected
Probable cause:
  1. Control unit software needs updating
  2. PCM or ECM faulty
  3. Fuel injector(s) faulty
  4. Ignition system - Ignition module, coil, spark plugs and wires
  5. Fuel system

Solution to p1351


P1351 just means there is a misfire. Was there a note next to the code stating which cylinder(s)? I would start by replacing the spark plugs, there could just be a fouled plug. If that doesn't help, pull the ignition coils and boots and see if there is oil in any of the spark plug tubes/boots. If there is, you need to replace the valve cover gasket.

02 passat rough idle cylinder misfires 1-3


did it misfire before the tune up? if not more than likely the firing order is wrong the wires we're put back onto the plugs incorrectly check the order other things that can cause this are fuel or even a vac. leak

My engine runs rough and the codes say p1341 and p1351


Here you go - this'll help you translate your engine codes. Looks like your getting a "Multiple Cylinder Misfire With Fuel Cut-off" and "Misfire Cylinder 5 With Fuel Cut-off". Hopefully you just need a good tune up, but this should point you in the right direction. Good Luck.

I've a problem with misfiring in # 5 cylinder -combustion failure


1. Swap two ignition coils between #5 cylinder and another one.
2. If the #5 cylinder misfire problem is still present you must check up wire by wire the electrical supply cable from the Engine Control Module (ECM) to the #5 ignition coil. Repair damaged wire(s). The last piece out of order will be the ECM !
3. Inspect also #5 spark plug if it is wet or dry. If it is dry then you must verify the #5 injector!
