Ok well I just replaced the ignition module, car runs sweet when I start it up. Put it in Rev. or Drive and hold the break and it misses a little, then when it gets a little warn it does that constant at idle. I got a Check Engine light, but its 11:10pm and I dont want to check that, I will in the morning. Any I ideas on what it could be?

Ive done all the sensors but the knock
Tune Up
New Accel coil packs

I will update tomorrow with the code.

it was a code 23, MAT, but thats because I had it unplugged, im am reseting the ecm now, any idea on what this misfiring could be?

bad coil

 

[penz88z24]

no, they worked fine on the older ignition control module, and they are brand new accel coils.

It doesnt miss that much only sometimes

Could be a bad injector shorting out. Do a search for "Steady miss at Idle" for details on how to test them electrically.

Good Luck
