| great car. has 57000 on it and had a sensor and a wheel bearing replaced. i drive the car in scca events and beat the crap out of it. pretty tough little car. if anyone is planning on racing the z on a road course, use some chains on the rear of the car to compress the springs if you cant afford the lighter springs. helps tremendously in cornering. it keeps the springs under a load without much rebound. incase anyone is wondering, got to 142 mph when i ditched the speed limiter. but that was turning 6000 rpm so i wouldn't do it for to long. only hit 135 until i removed the spoiler and closed off the radiator intake on the bumper.(CAR IS REALLY UNSTABLE AT THOSE HIGH OF SPEEDS ESPECIALLY WITH SPOILER OFF SO IF ATTEMPTING, BE REALLY REALLY CAREFUL) i left the opening at the hood latch and car hit 205 degrees but no hotter. | |

My 1996 Chevrolet Cavalier (2.2L) engine (30,000 miles) has a mildly rough idle (like little surges), that comes and goes from hour to hour of operation. My dealer changed the fuel filter and then told me that my problem was a leaking valve cover gasket that had allowed oil to foul the plugs, ruin the plug wiring, and ruin the serpentine belt. He proposed to replace the valve cover gasket, replace the plugs, replace the plug wiring, replace the serpentine belt, clean the jets, all to the total of about $600 (I said no thanks). I had already replaced the air filter and PCV valve. Only a minute amount of oil seems to have leaked out onto the block (at one corner only). The plugs are nearly new and look normal (no oiling or white deposit, and the gaps are okay). There is no oil on the wiring and the serpentine belt appears clean to me. Please give me your best guess of what my problem might actually be. Anyone? |

O2 sensor? When were the plug wires last replaced? Alternator checks ok? Just some thoughts. |
|
| if the plugs are not Delco platinum that is the problem. | |

Thanks for suggestions. I tried "fuel injector cleaner" added to the gas and the idle seems improved. If that doesn't do all I want, I will try O2 sensor, EGR valve, etc. one after the other. Plugs are nearly new Bosch Platinums (a brand I've had success with over many years). Alternator is fine. Wires seem fine ---- I've never had to replace plug wiring in any car I've ever owned, including my preceding four Cavaliers.

| I thought you would say Bosch Platinum that is sure your problem they don't work good in the GM cars. It has to do with plug resistance, its a long story. The j-body forum will tell you about them Bosch in the Cavalier. | |

| however, it seems strange that I never before have had trouble with using Bosch Platinum plugs in my previous four Cavaliers (about 200,000 miles of use). | |
