Hey ya'll. Got a question. My 89 GTA TPI 350 has been having some issues lately. I've had it for about a year and a half, and it didn't have such an awesome life before. It's always ran really rich, and I've had some issues lately with it not wanting to turn over. It'll crank, and die, and do that a few times until it floods, then eventually crank. I just replaced the injectors, found out they were corvette injectors, which I had figured because even adjusting my BBK fuel pressure regulator, it still ran really rich. I replaced them with stock TPI 305 injectors, and it hasn't idled smooth enough yet to adjust the regulator for the smaller injectors. That being said, one of the issues keeping it from idling smooth, is the OBD code 34, low M.A.P voltage, anyone have any suggestions? Haven't followed the wire yet, ran out of daylight. Any input would be appreciated.

 

Been so long for me, but I do know one thing, your '89 doesn't have a MAP sensor, Look for the proper codes for your year.

I think your code is MAF related...I bet if you searched for "Code 34" in this forum, it'd get ya on track
