My 97 Eclipse GS keeps stalling after the engine has been warmed up for about fifteen to twenty minutes while idling. I just replaced the IAC. I got a new ECU not too long ago and I'm wondering if I had gotten the wrong one, would this cause any problems?

the Code Might be the Crankshaft Postion Sensor, Definitely Could be ECU related also
Could be alot of things,
Make sure you have a strong flow of exhaust coming from the tailpipe
make sure the biss screw on your tb is set, double check ecu and wiring, check CPS, and see if cleaning your MAF helps, Check your fuel Filter and Fuel Pressure and Injectors

these could all cause stalling as well as lack of spark and make sure your timing is good

Fuel/air something isn't right. Did it run fine for a while with this new ecu and then have issues, or right after the new ecu install?
