I have a 1989 Toyota Supra turbo and my car doesn’t idle right

I have a 1989 Toyota Supra turbo and my car doesn’t idle right. It doesn’t kick up in the beginning of startup. Sometimes I have to press on the gas to start it. After I left off the gas from accelerating sometimes it dies. Thank you.”

Turbos are very touchy about vacuum leaks in the intake system, so check that out VERY closely. Cracked hoses, loose clamps, and broken or fallen off vacuum lines are the main suspects. And as they age, the air flow meters can often just wear out, making starting hard and causing stalls when you stop fast. Unfortunately your car is so old that a scanner won’t help you figure things out, as there isn’t any data available on them to get a good analysis. But, if you can’t find any intake leaks, you could just guess with a rebuilt air flow meter as you can certainly find one at a reasonble cost at any good foreign auto parts supplier (they’ll probably have to special order it in, but I got one a month ago for an older Toyota and it only took one day from California.)
