Hi guys, just bought 00 grandprix gtp 3.8 supercharged last weekend. The other night i was headed home from work and the car died at a stop sign. When i restarted it idled at 2g and chokes and sputters unless wot. when i got home i checked for leakes by spraying carb cleaner around all the gaskets and vac lines and couldnt get the rpms to fluctuate at all so now im thinking electrical. I started unplugging sensors to see if any of them would change rpms and nothing did. After all that i took it to a local shop to scan the codes and tp and maf failure. We cleared the codes and she ran great, till last night. I will be going to the shop tom morning to scan it again but not sure what the hell is going on and wondering if anyone had any suggestions or things to look for to help. thanks in advance
