O2 question
 

Ok, my check engine light came on. I went to autozone and it is po136 & p0141. It says it is the heater circuit and the electrical circuit both in bank 1. I have O2 trickers because of the prochamber. so am i to understand that it is the primary right passenger side o2?
thanks

Yes, your correct, its the passenger side Mixture controling O2 sensor that croaked on you.

That one has gave me some probs. I've replace that one twice now since I rebuilt the engine.

Unrelated but tied in. ONe of my friends with a 97 F-150 has a similar problem. Its lifted, and got long tubes. ALways passenger side front O2 sensor. Hmm..

I hate seeing that O2 sensor slow to respond code..always seems to happen around inspection time.

does anybody have the part# i need, i will probably get it anyways.
thanks
