SOURCE: ENGINE IDLES ROUGH, BUT RUNS FINE WHILE DRIVING

Check all vacuum lines for leaks. Check spark plug wires for and spark plugs that may be worn and causing idle misfire.

SOURCE: 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.

Rough idle


try cleaning out the throttle plate with some carburator cleaner and an old tooth brush (try not to get too much liquid cleaner into intake manifold). I have fixed this problem on many vehicles and is a very cheap thing to try first

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

Buick Century 97 runs rough and stutters when cold and gas applie


Your cat should last quite a while now it is replaced. I recommend testing coil packs and module. Change plugs and wires and double check your vacuum hoses.

Would 02 sensor cause excessive carbon deposits


Pretty good guess on the 02 sensor; this feeds back info to the computer to either enrich or lean out the fuel-air mixture. I don't think it will pass emissions testing if you suffer from those in your state but it has probably already eaten your catalytic convertor.
You could check this by picking a hill and having a friend trail you and sniff the air when you are pulling the grade and punching the gas; if the cat is still alive, your friend will be greeted by that rotten egg smell; otherwise he'll just see black smoke from your unburned fuel.

Well what now?


Could be a faulty Mass Air Flow Sensor, Idle Air Control Motor, just needs a tune-up, bad fuel pump, clogged fuel filter, bad spark plug, faulty computer... hard to tell. Take it to a shop to figure out what is wrong with it and if you are able, fix it yourself, otherwise let the shop fix it.
