Engine Performance problem
1993 Chevy Beretta 6 cyl Front Wheel Drive Automatic 194000 miles
I have a 93 beretta with the 3.1 V6 just bought it. It has a rough idle when braking for a stop light and while in gear sounds like maybe its missing a little bit. Also I just have replaced the MAP sensor with very little difference in it. IF any at all. And the tester codes come back to the MAP sensor. Even though I just replaced it. Also another question. The Air cleaner sensor. I think thats what its called. It plugs into the air filter box to read back air flow I would imagine. Now this seems to be plugged in but doesnt seem to make a difference. And also wondering if its supposed to have power going to that plug at all times? Or is it an intermittent type plug that only applies power during like accel. Or climbing hills?. Would I be able to use a light tester to make find out if it was getting power? And if so. What would be reason if it wasnt getting any power?
have the same problem?
