Hey guys -
I have a check engine light on currently (I know it needs to be read to be certain what it is). However, I have pretty much a fullback exhaust system on my car with the o2 sensors reconnected and I have drawn a check engine light previously due to it not being able to read properly. My question is, is there such a thing as a "heavy-duty" o2 sensor that I can replace mine with to avoid this? Or just get the codes deleted every time? It only happens when I run the cut-out open for awhile at higher revs. It usually takes a while to go off. Hasn't yet.
Please let me know,
Cheers
