Contour Enthusiasts Group Archives Forums General Troubleshooting Engine running rich - big $$$$$$

If an engine is running rich - what is a list of things affected and what happens first? I figure the Cats would go south fairly soon - along with various EMS sensors, and finally the engine itself.. Does that sound about right?
Having a go-round with a dealer who diagnosed an engine problem as "running way rich" - fixed stuff for big $$$$, then as soon as I got it back - had the engine light come on. Took it right back and they said I needed a new CAT and MAF for more big $$$.. My point - if these are logical things to be affected by the problem they diagnosed - they should have at least allerted me to the possibility of these additional costs - which could have drastically changed my decision to have the origional fixes performed in the first place. Just looking on some opinions on this situation....

Love this place - thanks to all who contribute!!!

Get another mechanic. Did this one not get the codes off the computer? Sounds like they're just swapping parts to make money off of you.

Check a mirror. Is "sucker" written across your forehead?

having a similar problem. dealer said i needed a new MAF. i said "no thanks" and did it myself. but i'm *still* running rich. not sure who to go to who can determine the source of the problem before they have replaced the entire emissions control system and PCM.
