Question about 1991 Buick Skylark

1 Answer

I have a 91 buick skylark. When I drive sometimes it won't accelerate like I'll lose power even if I floor it. And I died going up a hill flooring my gas. It's not a head gasket I already checked. My

Last night on the way home I'd put the car in neutral when I'd have to stop and I didn't have problems accelerating. But sometimes before I tried that last night it would lack power accelerating than it would be fine. Like a tug feeling. Please any ideas?

I think I would check the fuel pressure and the maximum fuel pressure from the pump.
I would look to data if temp sensor , map, tps,
lack of power can be cause by many things
hope it helps

Have you ever replaced the fuel filter? sounds like that may be the problem, it is under the car on the drivers side.

Check the mass air flow sensor (clean both heated wires with carb cleaner and Q-tip). Remember...cleaning does not always work...sometimes they are actually bad. Also check map sensor. Check for vacuum leaks at all hoses and fittings. If engine rpm drops sufficiently, engine vacuum will drop which may have caused a/c malfunction (controls work with vacuum signal) so I wouldn't worry about that 'till the run problem is dealt with.

The float is probably mis-adjusted in the carburetor.
Either that or the choke is out of adjustment.
It would probably bne best to rebuild it if you can, or have it rebuilt.
