1994 Camry acting up again

My 1994 Toyota Camry sometimes at startup is revving up to about 2000 RPM's then it will idle down and stall. It does start right back up though. I also notice when I rev it up and let it almost idle back down and rev it up again it will hesitate before reving up. The car has a new distributor, plugs, plug wires, distributor cap rotor bug,. I have also cleaned the idle control valve, throttle body, and the EGR valve. Any ideas on what is causing this???? The car is a 1994 Camry XLE with a 2.2 4 cylinder........Thanks Jburgess55 :mad:

My best guess, and it is just that, a guess, would be the ECT (engine coolant temperature) sensor. The ECU (computer) receives information from it to determine the engine temperature and therefor, the proper fuel/air mixture. When these go haywire many strange things can occur. You can test it with a digital volt/ohmeter using the manual at the top of this forum for the specs. You can also use the manual to show you how to test for trouble codes. I would try that first.

I checked the ECT this morning and it ohmed 2K at 70 degrees. So that seems to be okay.....Any other ideas??? Thanks for the help.......jburgess55

Did you run the diagnostics to see if any trouble codes are present?
