I had a minor fender bender a month ago and took some light front end damage. I basically had the front bumper and rebar and some other small misc. parts replaced. I drove the car home from the accident and noticed that it is idling a bit rougher and it vibrates a bit when taking off from a stop. I have gotten the car back from the shop and it has the same symptoms. However, when I'm at cruising speed, it feels like normal - good power and very smooth, no issues at all.

Here's my theory: I am thinking that the accident may have caused some erroneous sensor outputs back to the ECU. I plan on resetting the NVRAM and KAM. Does anyone buy this theory for why I'm running rough from a takeoff?

Please help!

 

Motor mount.

 

I hope you're right because my turbo kit came with upgraded motor mounts! (I haven't installed the kit yet)
