View Full Version : running rich??!!

04-04-2003, 09:15 AM
I have checked every possible hose connection etc. and all of them are in good condition. Still I'm running quite rich, like at half or more throttle there's grey & black smoke coming out from the exhaust system. Are the O2-sensors my "only" possibility....??
My car idles at 16-17vacuum and makes a full 15psi of boost when floored.

Any suggestions??

your vacum should be about 18 at startup (motor cold) when warmed
up should be about 20.maybe you have a vacum leak.

put plastic ties and or hose clamps on all vacum lines.

Possible you may need to clean MAF. Get a cotton swab and some alcohol or spray some brake cleaner at the filament.
