the revs won't drop, help...
Hey guys,
So I just got my car back yesterday. I was in a minor accident and had to replace the wheels and a couple other small things.. no engine or body damage.
My car struggles with dropping the rpms back to 1000.. When I come to a stop whether in 1st or neutral the rpms clime to 2200 and sit there, I have to put it in first and mess with the clutch to get them to drop down, then after a few seconds it will drop to 1000rpms on its own.
Also I have to give an insane amount of pressure to get the car in reverse.
what do you guys think??

Sometimes when the battery is disconnected, the C5 will "lose" it's idle memory.
You need to try to reset it. There is a procedure for this, but I don't know the exact steps. I think if you do a search here for "idle relearn", you may find it.

If it worked fine before you took it into the shop for the repairs, I would take it back and get them to look at it. I know you don't like the shop, but maybe their mechanics that work on the engine, etc. are better than the ones that work in the body shop.

Will disconnecting the battery affect my custom tune? Also will doing the ideal relearn affect my tune?

I will if I have to, I was hoping someone might of known of something I could try myself, or maybe seeing of my insurance will agree to let me take it to LG who originally did my tune, instead of taking it back to the collision center that did my repairs

check all around your air intake for a leak. If you're getting too much fuel ( high revs) it could be because you're getting in too much air.I don't think the two problems are related.

The shop is telling me they don't know if it's related to the accident or if its their fault, and that they will send a guy out to do the diagnosis. They said if the diagnosis comes back that its not accident related or their fault then I will be responsible for paying for the diagnosis and for fixing the problem.

Definitely could be vacuum, if there is a crack in a line or a loose fitting. I had this issue with a Porsche Turbo.
