    hello again, on my 03 when shifting it feels like the rear end wants to jerk sideways and I don’t mean in a good way when your mashing the pedal and shifting lol. Any ideas.

    Also yesterday I was sitting at a stop light and started to go and something sounded funny under the hood then all of a sudden it started popping and running really funny. As long as I didn’t give it to much gas it was fine but when I pushed down it started to almost bog down and start popping.

    Did you check in on the spark plug where the heli coil was done?

    Rear end lateral movement under load is usually upper control arm bushing.

    Yup, still all good. The car is running great right now. Seems when I let it sit for a few days then drive it, is when it acts funny.
