Morning fellas! Hope everyone had a nice easter? I had a good one, sunny & about 40* so me & my Z went out to take in the morning air.
Maybe mine has this off idle stumble & I never noticed it due to my never having had a pro stock motor! I don't remember having any stumbles until my OEM injector coils went away, at about 9500 miles. I used RC's as they were the only game in town at the time, 9/05. Ouch on the $ but at 30,000 I'm still smilin' as they're still good.
Your injectors will go eventually Jeff, but my Q's still stand about when the miss occurs.....all the time off idle, just when hot, just when cold, there is no miss at any other point in the rpm range??? Oh yea, usually if there is no SES light a scan really does tell ya what is working right and you have to reason it out from the data as to what is really the root of the issue.
Not trying to be a wise guy....don't take me wrong. I'm just trying to lend a hand.
Tom
