See if there is a code in the computer and work from there. Find someone with an OBD2 code reader. If I'm not mistaken an OBD2 code reader works on 1996 and newer models. Could be a bad coil and you don't notice it when you first start it until it idles down, to check for that, while the engine is running, pull each wire off the spark plug, Each time you do that you should hear the engine struggle. Then pick back up once you plug it back to the spark plug. If you pull one and nothing happens to the engine, that could be all or part of the problem. Hope this helps.

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

Here are the most common causes of idle surge, rough idle esp when cold, other symptoms include stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

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.

Autozone and similar stores will check the codes in the computer for free usually. That is the best place to start. Other possibilities are Engine Coolant Temperature sensor (saying the engine is cold when it's not) or excessive fuel pressure (bad regulator or blocked return line)

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.
