1.8 mazda engine won't idle down

[OrangeCrush 86]

I just bought my winter beater and finally got it to run; a 1992 Ford Escort GT. Everything seems good but it won't idle down from about 2000 rpms. If I turn the idle screw in all the way it comes down a to about 1500 rpms. If I screw the screw all the way in and unplug the IAC (I think it's a IAC) it comes down to about 1000rpms. If I take off the air tube that leads to the air flow sensor it will start for a few seconds then die. The air flow sensor is the old style with the door that opens. Any ideas or is anyone fimiliar with this engine? Thanks.

Sorry I accidently posted it in the wrong section.

Check for a vacuum leak. Spray some carb. cleaner around all the vacuum lines and intake gaskets. Just be careful near the spark plug wires. If the idle goes even higher, you've found your leak. Nick

Use propane torch unlit instead of carb cleaner.

I found the problem. I think it was the temp sensor. I replaced it and now it works great. I think it was stuck in cold start.
