Rough idle My 99 Buick LeSabre recently developed a rough idle and the engine light came on. Changed plugs and wires. The car diffently runs better but the rough idle problem still exist and the engine light came back on. Could this be a clogged fuel filter? If so, where is the fuel filter located?

1992 Buick Lesabre Idle Problem/ Bad gas mileage

If there is no "Check Engine" light try a bottle of good injector cleaner in your gas, or cleaning the throat of your throttle body with a good spray cleaner. If the "Check Engine" light comes on then put it on a code scanner and that will point you in the right direction.

99 Buick Lesabre Check engine light flashing.I changed wires and plugs but still misfiring on one cylinder, but all plugs are firing. Have 84,000 miles and has been running great until light came on and...

From the symptoms of the problem and the precautions you have done i think its time to check the EGR valve.Clean your EGR valve and then put it again. How handy you are in ding this?

As the check engine light is on did you scan for error code which will help you more specific to locate the problem.

97 buick lesabre 3.8 Idles rough and stalls out.

Fuel injectors go bad on these engines, you can find re manned ones for 30 bucks. If you have an engine light on get that read. Change your coil/wires/plugs also. Is the lower intake manifold gasket leaking coolant yet? You may want to get that replaced also. Check the TPS too (throttle positioning sensor) those will also cause your engine to act up

Car idles rough in park also runs rough in overdrive

Sometimes a rough idle like that is a fuel filter. As you've already done the plugs and wires the fuel filter would be my next bet.

1987 Buick Lesabre T stalling and running rough

I just had the same problem. Replaced the fuel filter,still crappy idle and no acceleration. I replaced the fump pump along with the wiring harness and the fuel pump screen and my cars purrs like a kitten,has back to normal acceleration and idles better than before. Hope this is some sort of help to you. I did it myself. Total cost, a little over $120. Good luck. By the way, your fuel pump should be pushing out about 65 lbs of pressure. is it ???
