09 chevy malibu

Asked by Aug 02, 2016 at 03:42 PM about the 2009 Chevrolet Malibu LS FWD

Question type: Maintenance & Repair

Hey so I just had my coils, spark plugs, camshaft
sensor replaced. Now my car is turning off when
I'm idle and it jumps when I'm trying to accelerate
after being at a stop light or when I'm driving in
general. I don't have a check engine light on or any
codes popping up my mechanic doesnt know what
to do now that there is no codes or anything.
Please help I need to get it fixed before Monday.

Was the camshaft sensor an OEM or an aftermarket? I have seen problems with aftermarket sensors especially cam and crank sensors.

Check for vacuum leaks, u might've left a vacuum hose off or has a hole on it

So I have more to my problem. My car does turn off and sometimes makes a noise like something is breaking when I'm turning but I couldn't get it to make that noise when my mechanic looked at it.....he ran another deeper diagnostic and it says that the coils, spark plugs, camshaft sensor were not even replaced and so he looked deeper on the computer and it says that the timing is off so now he thinks it's a timing problem but that would not cause my car to cut off so it could be part of the problem and somebody told me about a GM pass lock sensor needs to be overrided to make my car stop turning off. So I have no idea what to do

If the cam and crank sensor are not synced they that will cause a timing problem, but I think the big issue here is who loaded you in the boat by charging you for something that was not done. If the security system was active you car would not start at all, the only this could happen is if the system is starting too totally fail and that would be obvious to your tech besides putting out a lot of useless codes. So now your back to square one with another problem, noises while turning are usually bearing or C/V joint problems, higher mileage vehicles can have steering rack, ball joint and bushing problems. So now what to do? I would leave the car with your current tech, let them run it around to get it hopefully to fail and make the noises you have, then they can trace them down and give you real scope on your current problems. Then go after who ever sold you down the river on work not getting performed that you paid for.

If ur cam sensor was never replaced, that could be the reason it's cutting off. That sensor is part of the timimg system and if it's failing it's not adjusting the timing automatucally, the way it's supossed to. As far as the noise when ur turning, it's strictly mechanical most likely a ball joint or CV joint like tennisshoes mentioned
