Idle problems.
Short background info:
Car was an 97 SS 'Lude. I performed the swap over to a manual. Car ran fine for 3 weeks other than an Evap Canister CEL every once in a while. I was then a dumbass and mis-shifted. I pulled the head, had the exhaust valves replaced and then I re-installed the head. Ever since I put the head back on myself I've noticed what appeared to be power loss at high rpms like 6k and above. It also had the idle surges. The other morning I started my car and now it idles at 3k-3.5k rpms. Its insane.
Here's what I've done in attempts to cure it: Took off and cleaned IACV. Took off air intake and cleaned the throttle body. I've checked every vacuum and electrical connection. There is one that is broken but its the vac. line on the IAB Control Solenoid. I plugged both the line and the nipple at the same time with no change in idle. WTF is going on?? Please god someone help me before my car craters its main bearing on startup.
This has nothing to do with the mis-shift. The car has been running for 3 weeks since I put the head back on. The only problem its had is the idle surges. This happened randomly. Car runs fine one night....get up the next morning and it starts idleing at 2k. Its since been moving up....right now its at 3800 rpms. Also, when I push in the clutch w/o my foot on the gas the revs rise an additional 500 rpms before falling back to the 3500-3800. I'm sure its vacuum related and hoped somebody would know of some integral part of the idle system that could cause such a thing.
Oh and I did a compression check last week and came back with 185 across the board.
Alos...before this high revving business, if I had the idle set to the correct spot of about 700 rpms...if I accelerated hard then let off and pushed in the clutch it would die at times. I had to put it up to about 1000 rpms for it to not die off hard acceleration.
