ok well my car for sum weird reason is now vibrating when i shift into 1st gear and 2nd gear and it also vibrates the car when i turn off the engine. It never use to be like this with 1st or 2nd gear but i also can't ever recall the car vibrate when it turns off so i'm wondering if that's normal or not. I don't wana take it to the dealership yet b/c i am also trying to figure out some other problems that might be going on. I asked a fellow cobalt owner before about why my ride when i rev and shift into the next gear and put the foot on the gas, the car does a lil jerk and then starts pulling and he told me b/c it needs to get warmed up but when the car is warmed up, it still does the same thing from time to time so i'm wondering what else that could be?? i've had this problem before when walmart did my oil change and ****'d it up so i'm wondering if its b/c of that still. When i got it done @ walmart, it was doing the same, since the dealership found out it was way too much oil in the car so they drained a lot of it but since that day, the car will not perform as it use to be when i try racing it from time to time. Any suggestions??

Oh 1 more thing, any1 ever change the supercharger oil? my fellow cobalt owner told me to get it changed and i made an apointment but then the dealership called and stated that there is no need to, its lifetime oil and blah blah blah..

 

you shouldn't need to get your supercharger oil changed....not for a LONG time...

 

yeah walmart probally fucked it up. what oil did they use on your car?

 

It sounds like walmart used crappy regular oil instead of Mobil 1 Synthetic oil...Have the dealer do an oil change on it and see if that fixes it!

 

hav eyou put any mods on your car, even torque dampers maybe? I got some big vibrations from a torque damper that was put on wrong. also, make sure that walmart put in synthetic 5w30 preferably.

 

walmart has no clue about these cars unless you tell them. I actually had a dealership put regular oil in my car, but luckily i asked them about when i noticed how cheap the oil change was.
