My alternator failed a diagnostic test and I also have rough idle... I cleaned by IAC valve, didn't do anything.
Help would be appreciated.
Supercharged '02 SVT
MODS: Vortech Supercharger, VF motor mounts, 61lb/hr injectors, Trubendz 3" cat-back.
Oh, and the massive pile of uninstalled parts sitting in my garage...
I like to go fast.
