Chevrolet Malibu - Recent Questions, Troubleshooting & Support

with that little bit of info couldn't tell , you need to take it to a qualified repair shop.

There is a diagnostic trouble code stored in one or both of these modules. Electronic Suspension Control and Traction Control. You would first need to retreive the codes and then perform necessary repairs. Then if needed clear codes with a scan tool. Although I will say that usually the warnings will go out when the issues are repaired.

Transmitter Programming

Important:All transmitters which are to be recognized by the remote control door lock receiver (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.

1. Install a scan tool.
2. Use the scan tool in order to access programming: Vehicle Control System/Computer Integrating System/Module Setup/BCM/Program Key Fobs.
3. Press the START soft key on the scan tool.

Important:The scan tool must stay connected until all of the transmitters are programmed.

4. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
5. Repeat the previous step in order to program up to 4 transmitters.
6. Remove the scan tool.
7. Operate the transmitter functions in order to verify correct system operation.

Have you check for trouble codes? Have you check throttle position sensor?

Cylinder Head Bolt Torque Specification for the GM 3.1L and 3.4L Engines is as follows:

Tighten the cylinder head bolts to 44 ft.lbs (60 N-m) in the order to seat gasket.

Tighten an additional 95 degrees.

Then make a second pass tightening all the bolts an
additional 95°.

Remember, 95° is just a little more than a 1/4 turn, not 1/2 turn, or from 12 o’clock to 3 o’clock on the dial. Do not tighten beyond this.

check the nuts on the wiper arms and make sure they are tight. If the nuts are tight then a linkage on the wiper transmission probably came loose or broke. You'll have to pull some cowling off to access it.

Leave the cap off of the surge tank and let the car run till the thermostat opens a few times to allow the air to escape. Then, put the cap back on the surge tank before shutting the car off.

Could be the trunk release relay ,located in the rear fuse/relay box . It's under the back seat . trunk fuse # 22 10 amp - located in the same rear fuse box. Could also be the trunk latch actuator ,could be a wiring issue , could be a BCM - body control module problem . The trunk lid open button is a input to the BCM . When the BCM see's this input it energizers the trunk relay . Do you know how to look at a wiring diagram an use a voltmeter to test automotive electrical circuits ? If not ,your best bet mite be to take it to a qualified repair shop.

I have an 04 Malibu and when I get hard starts when I'm in the car I just press the accelerator down about half way and it always starts right up, some times I have to hold the accelerator down a little after starting to stop it from stalling but it is rare.

Just wash the car- Im not sure it uses a camera a lot of them use sonar- circle spot on the bumpers but you see one clean it with a phone screen cleaning kit but i debut they used cameras in cars to detect that because it silly not that i think about it, it could easily get dirty and interrupt operation- Id stick more with the sonar- either way do not look for anything to clean just wash the car as per manufacture specifications https://www.6ya.com/mr.mike

You got another computer from where ? Was it programmed ? Anti-theft system key's programmed to new computer also ?
