Hi,
I have replaced the fuel injectors, timing belt, and plugs. The air flow meter has tested ok. The car idles when warm from 750 to 3000 rpm's.
Any suggestions?

this shouldn't be in the test forum, it should be in someplace else, i'm not sure what it could be. does it calm down after a couple of minutes?

ICV or ICS depending if it was an 87 shipped in 88 or an 88 line. If its early 88 then there is an ICV or idle control valve, if its late 88 then theres an idle control sensor. Either way just spray WD-40 in it

Where is the ICV located? I've had a similar issue, but not as drastic. Idle jumps around from 750 to 1000 or so. The new exhuast I just got added helped a bit, but I'd still like it to be smoother.
