Idling Not Stable

Guys, I have a 1986 2.0Si 2nd Gen Model and currently I notice that my engine idles up and down within 500rpm when it is fully warm up and especially when my aircond is off. I wonder which part is defective....

It's a engine cleaner you get at auto part stores. A 1/2 in the tank 1/2 down the carb. It cleans out all the crap in the engine and make it run better.

Any experiance iv ever had with a honda and irratic idle was due to a bubble in the coolant system.
Just a thought.

could be a lot of things without testing the car theres no surefire way to tell you. possibly the IAC, possibly the carbon like was mentioned earlier, valves out of adjustment, problem with the fuel supply, ecu going out, really pretty much any sensor or wire from the sensor..

Thanks guys, will monitor for a while first as the car never start for the last 10 months. How to get the card back to its original comfort ride. Now hear some squicking sound and some sound from the under carriage too. Suspension?? I am looking for confort ride.

yea suspension probably.. one of the springs could be off its mount but I'm thinking more of the bushings need replacement.

My guess would be the IACV. Get it cleaned or valve replaced. If doesn't work then you need a tester and see what code comes up.

Also about that squeak, its probably your shock which is stuffed. Have the shocks checked. I'm pretty sure you can get it for free in some big workshops when you do the service there.
