Replying to: reece2 (Oct 19, 2007 10:32 pm) ok so i checked the air filter...a lil dirty but it's fine...i forgot to say that this car was just sitting abput a year before i brought it..i think im starting to narrow it down maybe...i just let the gas get real low but not empty..and now it really acting up..cant even really start it..so im guessing the fuel pump or fuel filter..i know something is wrong with my brake fulid because i can smell it..but the guy at midas told me that it wont make a car stall...so what do u think filter or pump??

Replying to: reece2 (Oct 20, 2007 4:12 pm) If it sat there for a year without being started and the same fuel was in the tank I'd say that could be a problem. Gas gradually changes into other things when it's been sitting that long. It may have partially clogged fuel lines or injectors. If it sat outside during that time water could have accumulated in the fuel tank.   I had an Opel years ago that sat in the driveway for over a year. Although most of the gas had evaporated by the time I got around to working on it the remaining stuff in the tank looked like maple syrup that you'd pour over pancakes. I had to clean all that out and ended up replacing the pump.   You might start with the simple things and add a bottle of quality fuel injector cleaner to the tank after you're sure all of the year-old gas is out of there and it's running on a fresh supply.   You might also replace some of the easier and less expensive things that I mentioned in the previous message like the PCV valve and fuel filter, especially if it had the same gas sitting in it for a year.

Replying to: garryh (Nov 20, 2007 9:19 pm) You put a 88 motor into a 95 ? What model engines are they. The injector power comes from the fuel pump relay, when the fuel pump is running you have power to the injectors.

#9 of 13 2003 Cavalier Dash Problems by atvman29 Apr 16, 2008 (10:21 am)
On my 2003 Cavalier, the instrument cluster seems to be sticky. The gauges go up but usually don't come back down when the car is shut off. Is this a common problem? I've called some dealerships and all they say is well fr $400 we can replace it. So does anyone know how to fix this problem? Is it best to get it replaced or get it repaired by someone who fixes them?

Replying to: KarenS (Apr 17, 2008 7:36 am) Sounds like a short inside the circuit board; the clusters on the 2000-2005 Cavaliers and Sunfires are known for shorting out easy causing all sorts of problems from dimming odometer lights, guages sticking, sections of the cluster not lighting up ect. The best fix is to replace the cluster (about $500 parts + 1.5 hours of labour at the dealer). Your best bet is too find a replacement cluster at a scrap yard. Make sure you get a cluster from a 2000-2005 model. Its simply plug and play.
