I am having high idle problems. The car idles at 2000rpm and will not go down even if it has reached operating temp. I've also noticed from my Field SFC that VTEC is activated.

From what a friend has told me, I've check the idle screw on the TB and it is all the way down. I've also bled the coolant and have checked the throttle cable slack. As far as vacum leaks, I could not check all, especially between the intake manifold and the SC but as far as the hoses, I've went around with a spray bottle and squirted water to see if there are bubbles and everything looked ok.

What I'm concerned about is the Field SFC VTEC light on. I was thinking that it may be the Field SFC and JRSC Map Controller in tandem that may be causing this problem, so I turned the Field SFC and on another try, I disconnected the MAP wire and ran it directly through the JRSC Map Controller only. Problem still not solved.

Anymore suggestions anyone?

 

Sounds like a vacuum leak.
What did you change before this happend?

 

I have a JRSC on my integra gsr and the same thing happened to me after a test drive at W.O.T. My problem was a coolant hose underneath the throttle body cable linkage. The hose was forcing the throttle cable linkage up thus giving it the high idle. But if you already checked then that would not be the problem. I know it sounds simple but that was what happened to me. I just tucked the hose underneath my little breather on my short ram air intake. Never had a problem since. I hope this helps. Good Luck!

 

The 4 rib belt ripped and cut through the power steering hoses. I had to take the supercharger out and replace those hoses. I'll monkey around with it more during the day hoping to find the leak if that's the problem.

bump for anyone else.
