Default Running rich, why?
Stock 5.0. I've replaced theO2s a couple years ago. I guess I need to check codes but any other ideas?
I pulled my H-pipe off today to gut my cats, well guess theF what, they already been done by a previous owner in the early '90s. Anyway,Ideas?

Try cleaning MAF wire, it has more to do with mixture than the O2's

I replaced it last year suspecting it was my culprit. I've replaced all those F'ing sensors on this motor. I'm like a dog chasing its friggin' tail!

This has crossed my mind as when the car is cold sometimes it will not idle up to warm up.

I pulled the codes last year and only came up with EGR bad. Replaced it and its sensor. I checked for vacuum leakes and replaced 1 line. I think one of these dang aftermarket sensors are crap. No codes right now.
