the check engine light shouldnt, however a bad o2 sensor could.

I heard that when the CEL is on, the car runs rich or the other way around? :dunno:

Ive never heard of the CEL itself causing issues...Now what causes the CEL to come on may cause a problem.

your gas mileage is gonna suck...i run rich like a mofo, but that might be a mix of a bad 02 sensor, no MILs, and longtubes..but my MPG is LOW.
