I have a 92 honda accord ex that the it idles between1000 &2000 when the car is in park
If it does that when the engine is warmed up (full operating temp.) it may be you iac valve, or your fast idle valve. They get gummed up. It also could be your PVC valve, but probably not.:
IAC in red. Fast Idle in yellow. Your PVC valve is plugged into the valve cover (the black hose in between the red and yellow in the picture) it simply pulls out. It should rattle when shaken.
Hope this gives you a start on the problem.
