1999 Chevrolet Blazer LS 6 Cyl 4.3L
vehicle ran fine until i change the cap and rotor what i did i cross firing wires then put them back how they should be
now P1345 light comes on and its getting harder to start..... do i need to replace the camshaft sensor ? or does the timing need to be look at?
i would say you crossed a plug wire. the firing order is built into the cap is just like the engine the front right goes to the front right the front left goes to the front left the short one goes to the coil. make sure the cap is on tight i have had one that was left loose and the spark jumped through the cap and was hitting the wrong terminals. if that happened you will see burnt spots on the cap.
