Re: Engine Studders After Adding Gumout
Iam gonna get into this and say that it looks like a vacuum leak to me. Get a vacuum gauge on the intake and see if you are doing about 18 - 20 inches of mercury at Idle.
If its low then check the seal from the throttle body to the intake assembly to see if it is split or cracked. If that is it, let me know and Ill tell you how to fix it.
