Hello all:

I have a 2003, 996 C4S. Approx 53k miles. And important to note, a TPC Super-Charger installed too.

I get a P1515 (Intake Manifold Switchover 1 Short Circuit To Ground) error code about every 50-100 miles.

I notice a few newer issues with a bit of a rough idle but it clears up after I reset the CEL. Next, I think I am getting what I imagine is Vapor Lock, where the car does not want to start after I have been driving and the engine is hot. I am not sure if this is related to the CEL situation or if it truly is vapor lock from possibly the Super Charger.

Is this CEL P1515 truly a situation where I have bare wire that is shorting out? If so, does anyone know where I start the hunt for this bare wire?

Any help appreciated! Thanks.
