95 Accord Erratic Idle
Mine is a 5-speed, 2.2 VTEC
Now I had not quite a breakthrough today, but The two holes in the throttle body (the upper going to the IAC valve and the lower to the Fast Idle Thermo valve), I read somewhere that the lower hole when the car is running there should be no suction, or very very little. Mine has adequate suction. (Its more than very very little in my opinion). Now I took the Fast Idle Thermo valve off and too the end plate off and found that the wax collar that holds the plunger in place was loose, or unscrewed. I used a pliers to screw it back in, I did not mess the wax collar at all when I screwed it back in. But now that did not help my idling problems when I put it all back together though, but I am assuming now that the Fast Idle Thermo valve is indeed bad since there is suction from the small hole in the bottom inside of the throttle body?
I dont have any vacuum leaks or anything, I spray carb cleaner all around the throttle body and the vacuum lines, nothing seems to stall it, and when I put my hand over the intake manifold when its running, it stalls. Now I have also checked the EGR ports, and I have cleaned them out.
Im gonna try to tune-up this thing this next week hopefully I will get paid, Im gonna put new plugs, wires, pcv valve, distributor cap and rotor button.
It stinks now too cause everything seems to be dumping on all of a sudden, the idle is whats really driving me nuts, but the shudder under acceleration is why I am gonna tune it up, and just tonight the ABS light has come on, and to top it all off, Ive been laid off! Ha, thats really great I tell you. Thanks for listening

A low coolant level can also cause a surging idle. Have you checked your coolant level? Or if the FITV is air locked/has an air bubble in the coolant lines it will not fully come up to operating temperature and it will stay open.
I suggest bleeding your cooing system. Also ensure that the hoses to the FITV are flowing properly. If the coolant level and hot coolant flowing to the FITV both check out OK. That's when you replace the FIT valve.
Also have you tried cleaning out the IACV?
