Code: too rich?

Code: too rich?

Postby AdventureJay [OP] » March 4th 2019, 10:23pm

Hello,

Two days ago I noticed a fuel line break and quickly fixed the damage with a piece of rubber fuel hose. Yesterday I noticed the check engine light on and got a read from Advanced auto by a man with a cigarette hanging out of his face. He said I threw four codes for being too rich. Also, last week, I installed a "new" 233c transferase so my Service AWD light is on. Thats is expected. Any thoughts as to what could be the culprit?

THX!!

Literally dozens of things that can make you run rich. the exact code number might help in the future.

Pull the ATC fuse in the engine compartment and that awd light will turn off

Crazy thing happened today, the weather let up from freezing temperatures and the check engine light went away. Could it have been my MAF sensor being frozen that was throwing the code? mystery machine.
