Re: 98 Accord 2.3L with erratic idle speeds

O.K. a little update. I purchased a new IACV and installed it on the car. While I had the old one off, I checked for battery voltage on pin 2 (middle pin) of the 3P wiring harness. It was 12.7 volts. I checked continuity on the black wire on the same harness as per troubleshooting guide in my Honda Shop Manual. I have continuity. Plugged harness into new IACV module and started car. It now idles 1600 rpm's after engine warms up. I unhooked the wiring harness while the engine was running just to see if the new module made any difference. The engine idle stayed high but started oscillating or hunting really fast and rough sounding. Put it back on, shut the engine off, cleared the code that I created, started it up and still idles about 1600 rpm's. Any ideas, the idle is now so high now that it is effecting how I brake at STOP signs and how the transmission downshifts approaching STOP signs.
Thanks for any ideas, guess I need to getting deeper into troubleshooting in the shop manual.
