So Im misfiring....

[JohnD1079]

Most of it is when Im idling and it happens when Im at a low rpm (around 1500) and Im easy on the gas. The spark plugs are new. The previous ones were ridiculously running rich. I think Its the ignition coil.

What do you think?

Oxygen sensor will throw a code sooner or later.
When running rich, mostly it's the oxygen sensor.

My opinion.

[Flatline]

If it happens more frequently, the try to go WOT and see if it helps. I believe the computer eliminates the o2 and some other things at WOT.


And Cakeboy, your sig is awesome.

probable causes: ignition coil, coolant temp sensor, intake air temp. sensor, fuel filter, fuel injectors.i smell a checklist!!! the list is endless since our cars dont have OBD 2 stock. makes pin-pointing problems can be suuch a hassle.

[JohnD1079]

Well from what I know, the ECU doesnt take in Oxygen sensor readings when the engine is cold, and I misfire in the cold as well. Also its something that gets progressivly worse, because its pretty bad now, especially under 1500 rpm.

[minoreparations]

do you have the proper spark plug gap?

[Law Grandeur]

maybe you just have a bad fuel pump?

[starchland]

egr, o2, timing? could be coil or ignitor possibly. maybe try disconnecting your o2 so it will go to safe mode right off the bat

[wed3k]

check resistance on wires.

Does your main relay click on and off as your engine miss fires?

I'm having maybe the same problem and have for a while.
Just replaced my O2 sensor...didn't help.
I have coils i can swap and my igniter is fairly new...looking at the dizzy with the evil eye

Here's my thread if that helps:
