Rough idle when cold 99" 1500 5.3l when warm runs fine
Question,
Ok when i started the truck this morning or any morning, temps about 50 degress. but when warm runs fine. Trucks over fueling
Truck chugs can't get it above 1500 rpms without it backfiring, but when warm it runs fine> It's got a code for system lean bank 2 sensor 2, but here's my question, cats have been hollowed out and rewelded, if i put a new oxy sensor in it will it fix it? or because the cats have been removed will it be a waste of my time? im not sure how these chevy's work> or is it even the oxygen sensor, guy told me when i bought it, it needed a new cam sensor, it was about 100k ohms off of resistance but didnt seem to change anything.
Help anyone?
Trucks got new fuel pump and regulator
