could I have a bad o2 sensor
My check engine light comes on some times, but if I get on the gas it shuts off. Heres my engine mods. intake,boost hose upgrade,dp,mp,cb,deletion of air pump. I ran the car with no air pump and with the stock cat for like 3 weeks before I got the mid-pipe on( If that has anything to do with it) or do you think maybe Im just running rich.
"I know you guys are gona kill me and probly bad mouth me, but im still running the stock ecu,but im only runnig 10 psi max" I bought a used after market ecu but it dont work right in my car. The idle bounces up and down from 2300-2600 rpm (only when the car is hot) So back to my question can a o2 sensor make your engine idle bad?

yes your o2 coud be bad as well as many other things, check for engine codes and also do a check on the o2 sensor. and please get a ecu of some sort u have too many mods for a stock ecu even at 10 psi u are flowing more air thru wich means u need that much more fuel.
