Question about 1989 Buick Regal
The car stalls out on a regular basis but before it does the low coolant and service engine lights come on. We have sprayed the carborator and put fuel cleaner in the tank however this will only work for a few minuetes then it will die again any ideas on what the problem may be?
Look at the wires right by the tank the clip rusts out in side found out when I replaced the pump all I did was wire them togetter

I'm not sure why you have a carborator on 89 regal, BUT if you haven't try replacing the spark plugs and wires you might want to try that if you have factory wire (the carbon composite wires it comes with are terrible). But that might help. If not maybe check and see if your fuel pump is working properly (ex. weak pump, bad fuel line, ect...)

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
