I have a Powerdyne S/C A4 Camaro with the extra fuel pump and FMU, which has been
running great since it was instaled over a year ago.
A couple of weeks ago the transmission would hold the gear until I pulled my
foot back and then it would shift.
This happened only briefly and then the car seemed to run fine.
After turning it off in a parking lot and then restarting it we found that
initially there was no throttle response but then it was there.
Got the car home no problem, but now when you start it up the idle will be fine and the car seems ok, but then
often it will go up to 1500-1600 rpm in park and die when put in gear.
If the idle is ok, the car will go a couple of blocks , and then start
cutting out and bucking as it catches itself.
The thing is it's not throwing any codes.
We tried my spare tuned pcm but that didn't help.
Just ran the same.
Checked the fuel pressure, MAP, MAF, changed the TPS and checked for vaccuum
leaks. It has a new opti and everything seems to check out.
We're kind of stumped right now and any suggestions anyone could give us as
to where and what to look for would be greatly appreciated
