I have a 91 accord wagon it idle between 1000 & 3000rpm's. none stop!
changed ECU , TB WITH TPS ,AND DIS . still idles fast. it surges back and forth.. even after it warms up..

turn down cold air intake
4-2-1 header
full muffler system from cat back

rest is all stock 2.2L motor trying to figure this before i do anything else to waste my money .

please if anyone can tell me how to stop this idle problem let me know so i can fix the problem.

I've heard its because of the Fuel injectors. Get some fuel injector cleaner. I don't think it's going to fix it totally but it'll sure help you out. I remember when that happened to me, I'd be waiting at a red light and it'd be so annoying I'd rev the engine myself.

Also, a must do:
Search the Accord AF site. I'm sure you'll find what you need instead of waiting for someone else to reply.

check your plugs and wires, your 02 sensors(you would probably get a CEL) and check for vacuum leaks.
