Vacuum Leak causing surging idle?
« on: February 25, 2013, 08:26:56 PM »

So I've been working on the surging idle for over a week and a half now reading all the forum posts etc...
So far I've:
Cleaned/Replaced IACV, FITV, Air boost valve, cleaned the TB, changed air filter, changed spark plugs, checked for vacuum leak, put techron fuel injection cleaner in, and put a new fuel filter in. So now I pulled the Vacuum Control Box off to check the MAP sensor and I can't really figure it out.
Oh and it only does the surging idle from 1500 to 1000 RPMS in Park and Neutral. No code is thrown. Any more ideas and I would be much appreciative! Thank you all for reading!

Mike

Look at the throttle body before I cleaned it too.
