Hi guys,
Anybody with the SC kit had rough idling issues? It’s trying to idle at normal rpms like 500 or 600 but immediately goes back to 1k rpm….
we are searching for vacuum leaks and it’s got new injectors and spark plugs as well…. Can’t figure out what is going so

not normal should be able to idle like stock

Southways

Need more info;
- What supercharger?
- Is the Bypass operating?
- Other mods?
- What have you eliminated?
- What is the vacuum reading at idle?
- What do the fuel trims look like?
- Does a small throttle position movement change the idle?

-PTG
-Yes we check
-actually running the same mods without SC, so it was only SC install
-Only the stock manifold intake sensor, which they said is not needed
- don’t have equipment for vacuum test, but checking for leaks… Any particular places to check for leaks ?
-we did send the fuel trims, think it was normal
- don’t recall, have to check on this… but the car is not settling at a particular rpm tries to settle but raises suddenly…
