First, have your daughter listen for vacuum leaks (young females generally have the best high frequency hearing) They will sound like a very high pitched whistle. Next, look for vacuum hoses that are damaged and leaking. Next, clean the throttle body. Remove the hose that goes from the air cleaner to the throttle body. Hold the throttle plate open and spray some throttle body cleaner (available at an auto parts store) in and scrub with an old toothbrush -- don't forget the top. There are other things, but these are the easy, common, obvious first tries.

I have an 1990 buick regal custom and stalls when im griving it then dies can anyone help me on how to fix it.


Sounds to me like a fuel filter.When was the last time it was changed?Because if a car starts and runs till you give it gas under load then dies it is a fuel problem.Start by chaging fuel filter and if problem still persists then next thing to check is fuel pump.

You might try a crank sensor, most of the time if you pull it out you may see a crack in it. It's between the top of the oil pan an the transmission, good luck.

I have a 1990 Buick Regal that stalls while accelerating. And then wouldn't start at all. After letting it cool for a few minutes it started but continued stalling. Before this started happening it was...


most likley a fuel pump issue. The only way to know for sure is hook up a pressure gauge and when you have symptoms check the pressure. If you spray some brake cleaner or quick start when it doesnt start and it does start then this is an indication of a failed fuel pump or fuel pump relay. If it still does not start when you spray then you have an ignition issue like a crank sensor or ignition module.

1995 buick regal custom running fine until I turned into driveway then engine suddenly quit , at same time all lights on instrument panel came on for just a moment. turned key to restart and nothing....


I'd first start with,checking your battery cables at the
battery. Make sure you can't turn the connections on
the battery posts. If they turn,tighten them up. Second, check the black ground cable going to the
chassis. Make sure that it is tight,and not full of corrossion,under the terminal.

1990 Buick Century 3.3L Check Engine Light comes on, stalls.


Need to check for fault codes. Possibly a faulty sensor causing the fuel system to run rich or lean.
