Question about 1993 Chevrolet Cavalier

1 Answer

93 Cavalier runs real rough

I have a 93 cavalier just put motor back in and got it running finally but it idles real rough but it drives fine just rough idle and not it is smoking real bad out the exhaust and spitting oil out the tail pipe when accelerating it hard and also smoking under hood where the exhaust manifold bolts to the actual pipe and i went through oil in the car very quickly. Im thinking valve guides any other suggestions.

    It was my dads car he lives 3 hours from me and he was driving it and he said it started running like **** as in idle and drivability and so he parked it and assumed it was timing he then gave car to me i tore it all apart and replaced timing gears and chain and head gasket and such and now this when i removed timing cover the timing was just fine where it should of been but i went ahead and replaced stuff and now this.

    Did you just replace a motor in it that blew up ?

Sounds like you left something out. check to see if you plugged in all the sensors and plugs, then check for any vacuum lines that were not replaced or may have been broken

    well if its spitting out oil then your piston rings might have gone bad or one of the valves could be stuck

97 cavalier starts and runs ok from a cold start after a few minutes of warm up it starts to run rough and miss. If i try to drive it it will start out ok but won't shift automaticly but shifts fine m


Sounds like possibly more than on problem, crankshaft position sensor, or ignition module likely on starting prob which maybe affecting shifting due to hard code in ecm, or shift prob could be shift solenoid in valve body of transmission. Both parts readily available from local parts store

93' cavalier, very rough running. Missing badly at all speeds and loads, including at idle in park. changed plugs and no change in symptons. Is this an injected motor (4 cyl)?


Yes it is fuel injected. If it runs but has no power there is a good chance that an ignition coil went bad and there would be no spark to two cylinders. Cylinders 1 and 4 are partners on the same coil and 2 and 3 are partners. Usually these cars if an injector goes bad they have an external leak.
You can try to listen to them by holding a screw driver to each on while its running but I don't think
that will be your problem anyway.Another giveaway for the coil could be a gas smell like it is partially flooded. When you changed the plugs were any of them wet with fuel ? There is also a chance that if the engine works ok at highway speeds that the egr valve is stuck open. This causes
rough running at idle and bad hesitation until highway speed is achieved. Hope this helps or let me know and we'll figure it out.

Yes, this is fuel-injected engine. Look for vacuum leaks and then consider replacing the ignition coil (located on back side of the motor). Just follow the spark plug wires and you'll find it.

Bad injectors causing the vehicle to run poorly can cause other damages to sensors etc. Buy a code reader and check the codes.

93 cavalier vibrating


your probably feeling a rough idle of the engine. need a tune up?

in park the engine is not loaded down, just idling at a low rpm=rough
in drive with brake on you have put some load on motor also at low rpm=rough
in drive on the road engine is at higher rpm, = smoother

generally 4 cylinder motors idle a bit rough, especially if one spark plug is not firing right or fouled or one bad spark plug wire. tune up may fix it. if it is not stumbling real bad or stalling then you can live with it.
