System to lean and rich CEL, any suggestions
Monday, March 14, 2005 1:46 PM
I've been throwing CEL codes for the past 2 weeks...at first it was system to rich, air intake temp. sensor, and a some sort of manf. controlled emissions code. I fixed the AIT sensor and i threw 2 new codes.....system too rich and system too lean, any ideas?

Don't forget to clear the code too. not only look at them otherwise you'll always get the same code over and over.

what does your data stream look like? vaccum leak maybe, rich on a map car, lean on a mass air flow car, but both most likely not a vaccum leak.
