You have a Magnacharger, right?

When the Magnacharger is installed the harness for the throttle position sensor has to be lengthened, check the connections where the harness was cut and spliced, I had to go back and redo one of my connections a couple months after I installed my supercharger.

I have had these connections redone, and soldered, so I'm pretty sure it's not that. I'm going to take the TPS off, and perhaps the throttle body and give everything a good cleaning and see what happends.

Dan, thanks for the threads, I'll go throught them the best I can.

Anyone else deal with this exact problem?
