Change fuel filter, and add a can of SEAFOAM to 1/2 tank of Premium gas. It's that simple. good luck.

91 olds cutlass supreme runs rough and wont stay idle.


If your vehicle is fuel injected I would say you have a blown fuel regulator. This would cause excess fuel into the cylinders (flooding) causing a miss and coughing and also blow fuel into the air breather. If will also cause the vehicle to run poorly and could cause the vehicle to stall. Also to much fuel on startup can flood the cylinders and cause the vehicle to no start.

My accelerator on my 91 chevy corsica is stuck and it wont disengage, when i put it in park the engine continues to rev up, any ideas on how to fix?


It sounds like the gas control lever under the hood may be sticking a little and not retracting fully to idle.Open your hood and have someone start your car.When they give it some gas you should see the actuator move which has a cable attached,probably located at the end of the fuel injectors on the driver side.It should be pretty noticeable as about the only moving mechanism when the gas pedal is pushed.Usually pushing the gas pedal makes the lever move toward the driver.Once you have found it,push down on it in the opposite direction as giving gas to see if the revs decrease back closer to idle.If it does,WD-40 on the hinge where it pivots may help.Spray it,rev it a couple times and check.Even if it works on the first try,do it a couple more times.If this does not work,please reply back and I will get an auto link to see what you posted. Good luck! Greg

1990 chevy blazer 350 ci throttle body fuel injected . the motor is flooding out u can see the injectors keep dumping fuel into the throttle body


Sounds like you have an injector leaking. Have someone just cycle the key on and off to run the fuel pump but don't crank the engine. If you see fuel dripping from the injectors, unbolt the injector cover on the throttle body, remove the injectors and replace the orings around the injectors.
