Recommended Posts

what do you guys think is wrong if anything? My car runs between good-great all the time. It does smell rich when its idling but that is normal for our cars. Any other ideas? no ses light or anything like that, just sort of pisses me off that i clean the shit out of them then the inside is covered in a HEAVY black soot a few days later. Thanks ya'll Jay

i had those trash bosch wiper blades, and the chattered across the windshield

 

i switched to anco wiper blades, which cost half the price of bosch, and they actually wipe the windshield correctly

 

along with being shit, bosch products are way overpriced

The engine shouldn't be too rich when idling. Make sure you don't have any vacuum leaks, they can cause a rich condition. Especially the hose going to the FPR.

FPR = Fuel Pressure Regulator

 

Check the vacuum hose going into the FPR. When you pull it, if there is gas in it, then the FPR is bad

the reason it would be rich is if the vacuum hose is unpluged it gives u 1-3 psi of extra fuel pressure

what he said, but the 3.4's a bit more touchy than the 3.1, so i'm gonna go with O2 sensor, cause my regal did the same.
