My Tacoma has been acting weird. Its starts and idles at around 800 most times. When i rev it up and drive it and clutch in it stays at around 1200 or 1000. Sometimes when i start it it will idle at 1000. I completely cleaned Throttle body and iac and did deck plate mod and new K and N filter I also tried resetting the computer by unplugging negative post for half hour i also unplugged efi fuse. The OHM reading for the TPS is around .94 ohms and it should be around 1.0 to 2.0 ohms. If i rev my truck up to 4500 and let it drop it will almost always go back to 800 rmp but if i rev to 2000 it stays around 1200. I am thinking its either TPS or IAC.
Any help would be greatly appreciated
