Question about 2003 Chevrolet Malibu

1 Answer

Car shakes, thumps and feels sluggish but idles fine.

Car was fine last night. Started it and let it run for about 15 mins before leaving for work. It idled fine. Then when I started backing out of the driveway I heard this thumping and the car was shaking. Felt like there was a bunch of weight suddenly added to the car as I was back out. Not much better going forward. I was sure I had a flat tire until I got out and looked at the tires. They all looked good. The emegency brake was not on. I didn't see anything visibly dragging under the car. Any ideas?

Im betting it may be a crankshaft position sensor thats on the way out. Most of the time vehicles will idle and start ok but under any load will spit, sputter, and have no power.

SOURCE: tire thumping in all 4 wheel drive

Coming from the rear? I could see the noise coming from the front if your axels are bad. It seems weird cause the vehicle would make noises like that in normal driving because they dont change when you switch to 4 wd

SOURCE: Rough idle, Car shakes, sputters and misfires upon acceleration

It sounds like you may have a problem feeding the fuel to your engine, I had the same problem with my 89 RS. All the 1989 model's fuel systems were recalled. I think you may need a new fuel pump. The fuel pump is located inside the gas tank in the rear of the car right under the rear axle. The fuel pump itself isn't too expensive, but with other small parts such as the electrical harness upgrade and fuel filter and the labor you should be looking somewhere in the $500 range. I hope this helps.

Could be, but you will need to check for trouble codes, since the engine light came on. The code or codes may help you troubleshoot it.

COLD WEATHER IF YOU HAVE WATER IN FUEL.ENGINE WILL SHAKE AND SPUTTER.TRANSMISSION WILL ACT UP IN COLD WEATHER.CHECK COOLANT LEVEL AND TRANSMISSION FLUID LEVEL WHEN YOU FIRST START VECHICLE.LET VECHICLE IDLE UNTIL IT GET WARMED UP.THAT SHOULD HELP.FILL UP FUEL TANK PUT A BOTTLE OF FUEL INJECTOR CLEANER AND GAS TREATMENT IN TANK SEE IF IT HELPS.
