CEL when idling long

[Beecha91]

Hey guys,

I get a CEL when I let the car sit and idle after its warm. Say I'm driving the car, and I hit a long stoplight or traffic, the cel will come on til I start moving again then itll go off. What could this be, any ideas would be great! thanx

fuel?

My car had a similar problem a few years ago after I put an adjustable fuel regulator on it and turned it up too high. I don't remember the code by number, but it was a rich mixture sensed by the oxygen sensor. I just turned it down a few PSI and it never happened again.

Ya the previous owner put a AFPR on there, but theres no gauge lol. So how would I go about this? Do you think it could be cuz im on 100 octane now, and the car was set up for 93? just an idea thanx!
