Here is the story. I have a 95 Hatch Si, with an OBD II GSR swap done to it. A little time after the swap my car started to idel all messed up. It goes from about 800 then raises up to about 1800 continuesly. I bought a new TPS and put it on, and it still does it. i am running a chipped P28 ECU, could that be a problem? I really want to fix this B.S. it is strated to get old fast. Any help would greatly be appreicated.

Check map sensor, tps, idle air control valve, and make sure IAT and other sensors aren't switched. Even check for loose ground wires. Have you tried using a different computer just to check if that was the problem? Try cleaning all the sensors, etc. Good luck.
