2003 GMC Safari 4.3L Hesitation, Cuts out, Stall, MIL Lamp on, P0341 VIN: 1GKDM19XX3
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... Trouble codes: P0341 (CMP Sensor Circuit Out of Range)
