My 1997 Monte Carlo has been running really bad after I removed and replaced the upper intake gasket. I removed it to check for a fuel leak. Anyway I ran the codes today and got P0108 (MAP) P0102 (MAF) P0121 (TPS). Any idea whta could cause all of these at once? It ran fine untill recently. I have been told to check the fuses, clean the mar, to check wiring etc. Thanks CJ

If the codes were not present before you did the gaskets, it sounds like you're on the right track.

Recheck all your work and check wiring for cracks, frays, etc. as well as connections, fuses, etc.

Make sure you have no unmetered air entering the engine.

Good luck and keep us posted.
