my 05 acura rsx is running really rough after changing motor mounts. jack engine and trans up just an inch or two to take pressure off of mounts and now it runs like there is a vacuum leak. are there any lines or something I might have pinched or pulled off while doing this. base model with auto trans. really frustrating driving this way.

i usually check for vacuum leaks with carb cleaner. is your idle speed higher than normal. usually it will be higher with a vacuum leak

Did you put in aftermarket mounts and not stock. If you did, this is how it will be

I'm thinking the same thing.

Exactly.

Running rough and vibrating are much different.
