I wonder if they forgot to disconnect wires when they uninstalled the theft system and something is still messed up?
The IBS connector on the battery could be an issue also depending on how things were wired
Have you changed the timing belt and tensioner?
If not you could be looking at major engine issues especially since it was ran with no oil in it ??
That's not good either
The lines were good..I spray under the car also.....the mount was a large one I dont know which one it was as my mechanic got it as he noticed the issue when it was on the hoist the rubber bushing was pretty well disintegrated.
