finally finished up the FD UIM swap and car starts but wont idle, so how do i check for vacuum leaks if car wont idle? ive heard of using carb cleaner and spraying and were idle rises theres the leak but my car wont idle. or can i check anything else that would cause the car not to idle

any help would be appreciated

get someone to hold the gas while you spray for leaks.

so what do i look for? will the rpms rise?

thanx

yes, the rpm will rise and the idle will smooth out momentarily.

if you use some starting fluid and spray around, you'll notice a rise in rpms when you spray it over the leak.
