1988 yj 2.5 TBI
this thing has been trouble free for a long time, now i have a problem i cant figure out.
it was pulled into the driveway a bit sluggish, so my wife left it and took the truck to work.
i went out to see what was wrong with it, assuming she ran it out of gas again.
it started right up for me, but the ildle roared to about 2800 and stayed there.
it appears that the Idle Speed Actuator (isa) is keepng it there.
i figure, pull the plug and it will let off, right? NO.
i commence to pulling plugs on the rest of the crap that is on the throttle body, and there is no change.
this damn thing still roars at 2800 rpm.
so i put them all back... no change.
any thoughts on this thing?
there are no vacuum leaks that i hear or see.
What is all of this talk of Savvily designed products?
