I have a 1993 Toyota celica the problem i am having is the car runs and idles fine for a while but then stalls out... Before its about to stall it will idle at 2,000RPM just wanted to see if anyone could help... I brauoght it to a Specialist and they said they could not find the problem.... I baught a new map sensor put that in and it did shit.... I also decided to buy a new ECU didnt put that in yet wanted to know if i should do that. Thanks to people who can help me out much appreciated!

Clean the throttle body and every hole in it. Remove battery -ve before you start to reset ECU.
If it still fail, get another ICV. The green thing at the bottom of the throttle body.

The ECU is expensive and may not solve the problem. You have replaced the two most logical parts MAP and IAC valve. Rather then guess, read up on this engine. The Camry uses the same engine the manual link is below. Or take it to a Toyota dealer for a diagnostic.
