1987 keeps stalling

[grandpadon]

My daughter has a 1987 Buick LaSabre with 77000 original miles. It stalls and then you can restart it The car might stall again right away or might go a block or more without stalling. Has new plugs and wires, new fuel regulator and filter. After the regulator ran ok for a little while but started it again. Took it to a garage and they said the car ran fine he recommened a garage with more computer info to check it out. It spent five days there and a mass air flow sensor was put on. Drove the car approx 15 miles, made 2 stops and then the car stalls again. Restarted, stalled restarted went a couple of miles stalled, restarted stalled did this about five times then he ran fine for approx 6 miles. Can someone give me an idea of what might be going on. We can not afford to fixing this car but she cannot afford a car payment. Any help would be appreciated thanks.

I take it that there must be no check engine light or codes registering? I had a similar problem in an 87 Oldsmobile and it turned out the be a broken ground wire in the trunk. It was the oddest problem. I happened to notice the wire was broken where it connect to the ground bolt. Touched the wire to the metal and it ran fine. Another time, it registered a code that said it needed either an ignition module or a computer. I replaced the module and it turned out to be the computer, which was $99 for a remanufactured. It could be one of many different things. If you can check for codes, that might help. Also, I would check the fuel filter and fuel pressure. Does it put out a lot of black smoke, or is there any other symptoms that might give a hint as to what it might be? Does it stall when it has not warmed up, or is it only when it's hot?

It could also be your crank position sensor. You might need to take it to a dealer for diagnosis (or any garage with the proper scan tools/software.)

There is no way to diagnose it accurately as is without a scan.
