2003 GMC Safari 4.3L Hesitation, Cuts out, Stall, MIL Lamp on, P0341
Posted to GM Driveability on 11/12/2022 24 Replies

This is driving me crazy. Fuel trims are +-2. O2 sensors are responsive. I replaced the cam sensor and the problem code remains. In open loop(c0ld) it runs smooth but once it hits closed loop, sometimes it runs fine and sometimes it runs rough and stumbles...
