PostSubject: Cold engine stumble, with drivers little backfire   Fri Aug 20, 2010 6:16 pm

I took off out of the driveway last night, had a bit of a stumble, then a pop (backfire) from what sounded like the drivers side. It goes away when it warms up. But the car seems sluggish, more so than my 95.
He just changed the plugs, no opti though. I'm wondering if i've got a bad wire. But doesn't explain y it does it when its cold only.

On another note, this has a PCM tune from PCM for less, and it shifts WICKED hard. Can i retune this to shift easier? I can't believe he drove it this way for years, because it hurts my neck on a good hard pull into 2nd and 3rd.

Thanks

Same problem here, but doesn't stop when warmed up scratch

If it's missing when cold then that would lead me to think it's related to being in open loop mode. That would make me think it's an issue with the maf, iat, or some other intake related sensor. I may be way off but it's where I'd start looking.

I've had bad plug wires cause problems according to how warmed up the car is...so actually it could be that too I suppose...

It's really weird, I'm not sure what's going on. I'll check those things.
