Question about 2003 Chevrolet Malibu

4 Answers

I own a Chevy Malibu 2003 LS, fully loaded and 54,000 miles. I was driving approximately 20 mph in a 45 mph zone. There was a car in front of me going extremely slow so I sped up to approximately 40 mph to pass. My car continued to speed up. I hit the brakes and immediately after taking my foot off the brake pedal the car sped up as if the gas pedal was floored. I hit the brake pedal and shifted into neutral after going almost 80 mph. Scary as my 18 month old was in a carseat in the back. I took the car to a Chevy dealership who advised "You must have had the car mat stuck in the gas pedal". Trust me, that was not the problem. Can anyone help me???

    I have the exact same issue with my 99 Chevy Malibu. It usually starts revving at some point when I'm freeway driving. I don't actually hear it revving until I've come up to a stoplight. Immediately, I can hear it and if I don't stand on the break, it would lunge and take on its own. I have to pull the car over somewhere, shut off the engine and then start it up. Once I've done this, then it will idle just fine...until the next time...and I never know when it's going to happen.

Do all of the other sugestions, they are probably a lot cheaper.
Then i would i would have the cruse control looked at.
I had a simular problem with a 1983 Oldsmobile, i caused the problem in my case, i made some adjustments to the cruse control took car for test drive .
I turned around in parking lot when i put the car into reverse, it took off ! with out warning,i got it stopped (barely) i un hooked the cruse imeately, and never reconnected it .
It may not be the cruse, but i would have it checked

Had the same problem with mine in the summer of 2004. There was a recall by GM on the gas pedal because it was sticking in hot and humid weather.

Hi,

Ok it sounds as if the throttle gut stuck . This could be a bad throttle cable or return spring on it but i would say the cable is getting bad inside of it where you can not see it . I would recommend replacing the cable first.

2004 chevy malibu 2.2 driving 60 mph shut down


either you have a fuel pump that went out, or your fuel pump relay went. These fuel pumps last around 100,000 miles, so if you're way under that, it's more than likely the relay, if you're close to that, it could be either.

When accelerating from approximately 0 - 20 mph


My immediate quick test would be to move the front tires to the back (and backs to front, of course) then try it out. If the vibration is still there but feels like it's coming from somewhere else (vibration could feel like it's in in steering wheel or seat), you've got a broken belt or bent rim (wheel). Don't want to get your hands dirty? Get all 4 wheels balanced -5 to 10 bucks per wheel.

My 2003 Chevy Malibu suddenly lost power climbing a hill. The engine light started flashing. I was able to drive it home at 30 mph.


Could either be the ignition system - ie, coil packs, fuel filter, fuel pump, or bad gas. Was it sputtering?

2000 Lincoln LS rumble from 40 - 45 mph


See If the pitch changes when you swerve the car from left to right. You don'e have to swerve hard enough to scareanyone, just enough to load one side more than another. If the pitch changes, you likly have a bad wheel bearing or tire. Tires will make any noise a wheel bearing will so switch tires first side to side and see if the problem fgollows the tires. If not then check the wheel bearing.
Also and maybe first:

The fact that the noise is limited to such a narrow speed could also indicate an aerodynamic issue such as a roof rack or bike rack or somthing like that having moved and is now vibrating.
