Hello I have a 1988 Delta 88 and the car runs great! But now I am having a problem with it shutting off randomly. I change the plugs, wires, crankshaft sensor, temperature sensor. And cleaned the mass air flow sensor and still the car shuts off randomly. It shuts off but if I wait about a minute it will start run for a mile or two and shut off again. It doesn't do it all the time but it's becoming more frequent. Can you tell what the problem is? Thank you!

When it doesn't start, check to see what is missing. Is it spark or fuel.

Let me know what you find. Also, let me know if you checked for trouble codes.

Well I checked and the fuel is good (fuel pump and pressure) and spark is also good. I was told that my MAL mass air flow could be bad. Help!

It could be bad. However, there should be a code in the computer identifying that component as having failed. Have you checked for codes?

As far as the fuel and spark, was the pressure within the manufacturer's specs? Was the spark a good hot blue spark?
