P0353 Code Help I have an 05 Silverado 5.3 V6 swap with a turbo. About a week ago it started idling rough and final showed a code in the blue tooth scanner P0353. I have tested all the wires for conductivity and OHMS from the PCM to the plug on the coil pack and they all test fine. Replaced coil, wires and checked plug this has not fixed the problem.
