91 liberty hunting, hesitating idle (video).
Posted: Mon Feb 20, 2012 4:41 pm
G'day folks,
My lib has gone angry on idle.
This motor run 100% beautifully before the car was left in the garage for almost a year. Upon firing it back up the idle has gone to complete sh*t, where it hunts, surges and then hesitates almost to stalling before picking back up again and cycling through irregularly.
I've already ready removed and cleaned the throttle body, TPS and IACV and PCV valve. All vaccum hoses are in good condition with no leaks. I've checked the idle with the IACV disconnected and it's still rough. Good spark at each lead on both ends, a little sus on fuel as it's been sitting for so long.
I've put a video up to help you guys understand what I'm talking about.

Any suggestions on where to from here?
Cheers,
Owen.
