running rich

[malin819]

1990 talon fully buit motor

Aem ems with sd

When the car cold...the af is between 14.7 15.3 but once its warmed up, 12.8 13.5. Thats for idle and cruising...

Could it be a bad o2, wideband problem, coolant temp sensor?

Only running rich when the car is hot

What w/b are you using it may need to be calibrated.

You can't calibrate a UEGO. Sounds like a front o2 problem.
