    Do you know what the code is that is causing the check engine light? It can help in the diagnosis.

What is the code? I suspect the MAF (mass air flow sensor) but until I know for sure I am only guessing

My 1999 buick century started making this squealing sound when ever i hit he gas, but stops when i break, what could it be? also, when i push on the gas pedal, i hear this water gurgling type sound co

the sound is from loose belts ( poor condition belts) that slip from the acceleration. Check power steering belt, ac belt and generator drive belts of if one belt check condition and tension.

1999 buick century won't accelerate over 30 mph

is the check engine light on ! if so have it scanned to find problem code. auto-zone will scan for free, with a OBD-II scanner, as long as light is still on. if vehicle was running good before this happed it could be a few things wrong. tuneup, airfilter, throttle body dirty, fuelpump ( low fuel pressure ) or a clogged uo fuel filter. hope this helps! even a dirty maf sensor will cause, poor acceleration.

97 buick century, oil light started flashing, check engine light flashing car shut down on the interstate. what can i do?

Go check your oil first. If it is low or absent then you need to go get some! The car needs 2-3 quarts to get back into range at the least. Then try starting the engine. If the car starts and the light goes out you can drive to a mechanic and have the check engine code read to see what else is wrong. If the oil light stays on....call for a tow truck! You risk serious and complete engine damage if you drive any further...if you havent already!

Be careful and good luck!

My 1999 Century gives me difficulty staying started after fueling

Sounds like a fuel pressure issue. When you release the pressure in the fuel tank, the pump may have difficulty re-pressurising the system. Another possibility is the the one-way check valve in the fuel pump is faulty, and fuel drains back to the tank while you are fueling. There also exists the possibility that the tank is being overfilled, and the fuel return line is being blocked, causing an OVERpressure situation in your fuel rail, which might explain why the engine runs when you hold the accelerator pedal down. How about your fuel filter; when was it last replaced? Is the check engine light on? Take it into a qualified garage and have the codes read. Maybe the mechanic will be able to point you in the right direction.
Hope this helps!

I have a 90 buick century custom 6 cylinder and when I accelerate the car shuts completely.

Check fuel pressure after replacing filter. Fuel pump may be going bad.

Car problems and

good question, but they are not related, they are on 3 completely different circuits and un related in anyway, the gas guage is most likely the sending unit in the gas tank is defective, the check engine light will require a trouble code test of the system, any Kragen or Autozone can do this, it's free.
