My daughters 95 accord w/4 cyl v-tech has surging idle. I've flushed coolant and checked for vacuum leaks. the car starts fine but within about 5 minutes the idle goes back and forth from 1,000 to 1,200 rpms. While it's doing it if I disconnect the Absolute Pressure Sensor it misses a little then settles down. Nice quick fix but I DON'T LIKE DISCONNECTING THINGS because I don't know what new problem I may create. I want to clean or possibly replace the IAC but the engine is right up against the firewall and very hard to get at. Is there an indication of what may be wrong by unplugging the MAP sensor? Oh, I did replace the MAP sensor.

 

I don't know to be honest, I have the same problem on my car when the weather is below 65. I have the skunk2 I/M on my 95 Accord and it's even harder to get too. I'm thinking its the IAC tho to be hoenst. Hope that gives you some insight. Good luck, maybe someone else on here will chime in.

 

look in the faq's for "how to clean fitv" you'll want to take it off and turn the wax pellet clockwise
