P0352 code
It's a 00 Silverado 1500, lq4, 4l80e, ebay gt45, 80lb injectors. I've checked and cleaned grounds, replaced a couple grounds, new coils, new wires, new plugs. Checked the plugs to make sure pins were tight. Still get p0352 error. Truck runs fine though, no misfire counts in hptuners. I will clear the code and within 10seconds it shows back up. No check engine light, just a pending code when I pull them. What am I missing ?

If there is enough wire length to swap #2 with #4 on the coil end you could do that and then swap red 29 with red 67 in the PCM connector. If the fault stays on #2 coil then the driver in the PCM is probably bad. And with those mods I would guess it is tuned in SD. Misfire detection is disabled on some PMCs/OS in SD.

The truck drives fine otherwise, no hesitation, no rich conditions. Doesnt act like its misfiring, no skips or anything. I had an issue with plugs being gapped to far and boost blowing spark out, so I gapped then to .030. Cleaned up plugs and then this code appeared. Figured it was wiring but checked everything over. |
You could say a coil driver going bad is rare until it happens to you. Per Mitchell: DTC will set if PCM detects ignition control circuit is open, grounded, or shorted to voltage within one second.
