2009 Chevrolet Lumina LTZ random acceleration problem and Cruise Control

5

Asked by Jul 21, 2013 at 03:47 AM about the 2009 Chevrolet Malibu LTZ

Question type: Maintenance & Repair

I have a 2009 Lumina LTZ 3.6L with 2 main problems...

1. The acceleration suddenly stops randomly when my feet is on the pedal. This
happens between any speed... 0-60 or 60-100KMPH... It happens completely random
to me which is why I fail to explain it to any technician. The tech said there is no error
code so he cannot do anything. I have to raise my feet off the pedal and give it another
go to engage acceleration.
Its not like the acceleration doesnt work at all.. .maybe it goes 0-60 or 70 and then
stops reving... I will have to give it another go to continue... ANy idea what this could
be?

2. My cruise control does not engage. The visual indicator says Cruise On, but it does
not say Cruise Active. Earlier, it used to say Cruise Active but it used to dis-engage 5-
10mins later. Now it doesn't go active at all. The tech again said.. no error code for this
so cannot tell.

They usually recommend some random part to be replaced but they are not completely
sure if that would do the fix and result in a hefty bill. Any insight on these problems
could help me alot. Thanks in advance.

Your car has an accelerator pedal position sensor. That is to say there is no throttle cable. When you step on the gas this sensor sends a signal to the computer. The computer then "revs" the engine accordingly to make the car go. Sounds like this sensor is failing. I bet once you get that straightened out the cruise control problems will go away too. In the meantime check all of your brake lights. Make sure they all come on when the brake pedal is depressed. On my '93 Chevy Caprice if the third brake light burned out the cruise control would stop working until I replaced the bulb. HTH. -Jim

do you meen the O2 sensor
