My 89 honda crx High Fuel runs excellent except for one issue. When its warm sometimes it will idle rough, that rough idle lots of old hondas seem to have. I have been around this issue for over a year and still have not fixed it so I figured I would see if any of you guys have ever had the same thing. It does a real low rough idle, wont die but very low and rough. The car gets 50mpg so I dont want to just replace the engine with something faster, rather fix the idle. I have been through the ignition (new distributer, wires, plugs, cap, rotor), fuel (new injectors), and iac valve, and put a new egr in it a year ago to pass emissions but still no change. Any suggestions?
