I had a TPS CEL and my car drove/idled fine. Today, I fixed my CEL for TPS, but i have a lopping idle again. And after a few minutes of driving i had a CEL for for my secondary O2 sensor. The engine also seems to hessitate for a second. on dropping rpms when the clutch is depressed
Can an O2 senson effect the idle, or cause it to lope? If not, what else could be causing the idle problem.
