Your 1995 Tercel is dying out when you come to a stop after driving for a while and it's running at driving temp it seems like it's got a very low idle but when first starting out it idles fine?

Answer 1

When an engine is cold the carburater or throttle body (whichever you have) is adjusted to raise the idle speed slightly. Once it warms up the engine is suposed to idle a little slower. If you're having trouble maintaining the engine idle speed, you may need to find the source of the problem. It could be as simple as a worn throttle body, partially plugged air filter, low fuel pressure, or a poorly adjusted idle speed screw, depending on what your vehicle uses. Unfortunately, it could also be more complicated, such as poor compression, stretched timing belt or a weak or mis-timed ignition system. Start with the simple stuff. Get it warm then let it idle briefly without the air cleaner. That will tell you if your filter is plugged or you have some other obstruction in the air supply. BTW, don't let the engine run without an air cleaner if the air has dust or other particles floating around, in other words, don't run without an air cleaner if you're in a dust storm. After you've checked the air supply, you could check the fuel pressure. If that's not it, run a compression test.
