Cat and emmissions
If a cat is going bad, or already there, would both CO and HC be unusually high? My HC is slightly out of range, where as mey CO is very high.
Would a dirty air filter cause CO's to be that high?
Im trying to rule everything else out, before I assume cat. Ive done plugs, cap, rotor, and clean air filter. I want to also check FP and replace O2 sensor. TPS is good and was within range.
