you have wiring issues for sure, get those sorted out first

The schrader valve is after the injectors and its on the return line before the pressure regulator.


As far as your car and its running issues- the ASR steps in and retards the ignition to control the wheelspin- since its playing with your ignition I'm not surprised that you are getting some knock signals.

As much as I hate to say it, but I would double check to make sure that your opti was installed correctly. If it was off a little the computer can compensate for it under certain circumstances but it isn't a miracle worker. Sometimes it can be as simple as that-

but it cant be off, it has that damn dowel that only goes in one position, I already had to redo it once, I'd be damned if I have to take that apart again...... could you ellaborate what you were saying about ASR? the car does seem to run better with ASR off, as I posted in the new thread on this subject: http://www.camaroz28.com/forums/showthread.php?t=557564
