Well I got a used but working OVP and also idle control valve installed them both and still no change. I installed the ICV first. Started the car and it seem to idle pretty good till I revved the car up then it hanged at 1500 then down to 500 and back up. Same ol stuff! I then popped the OVP in and had no change at all. One thing I have been noticing with the idle is the economy gauge stays about mid way when it's surging. Also when I barely apply the gas it goes all the way in the red. Doesn't seem right. I don't think it's the a vacuum leak because of how erratic it is. It will surging for a minute or two then stop. It might start again though at anytime, also when it's idling decent if I rev it up to about 2000-2500 it will usually hang on the way back down at 1500 and then surging a couple times.

Bad thing is it seems any fuel problem seems to cause a surging idle after reading these forums.

Can any of you guys that are experts on idling maybe do a step by step on the steps to remedy a problem like this as well as the correct values the sensors should spit on the voltmeter.

Also anyone know where I can get a 88300e service manual on cd at??
