Changed Ignition Coil, Changed Spark Plugs, Still Getting a Misfire!

[FACT]

I recently made a thread about my misfiring engine (a4 1.8tqm) and it was suggested that I change my ignition coil and/or my spark plugs. I did both, and autozone is still reading a cyl. 2 misfire. I also tried unplugging my MAF and that made no difference. Does anyone have any other things I could try in order to fix this?

did you try replacing your coil packs? I had similiar problem replaced coil packs and no more problems.

If you checked your spark plugs also, may want to try Lucas Fuel Injector Cleaner. Make sure your plugs are clean. I read threads that a bad coolant temp sensor can also cause misfires.

The ignition coil is the "coil pack"... technically our cars don't have coil packs as I recently found out lol

[baboom]

we have a coil on plug set up.. is the a short somewhere on your wire to the coil pack.. ICM could be the problem..

^He has a DBW. But good call on the short.


Ignition Coil Pack (meaning a pack of 4)

Ignition Coil= 1 coil

move the injector. if the misfire is still there, i would suggest maybe a leak down or compression check,

I'll put $100 on the Ignition Control Module.

edit: Or do DBW have ICM's?

lol been discussed. his car is a 2001 so no ICM. I thought that too but i like to skim posts and not read important info
