Car stalls after 10 minutes
I got my car back after it was in Auto body jail for 11 months. It starts fine but after about 10 minutes it stalls rather abruptly. It will cut out then run and cut out. It has fuel injection on a HO 454. Voltage is 13-14 volts, fuel pressure looks good. It almost acts like ignition. I was wondering if it could be a bad O2 sensor also. Any thoughts on what it could be?
