Hey,
I'm new here... hopefully I can get some help from someone on this.
I have a 1992 Accord LX 5MT with 210,110 miles. The engine was replaced at about 120,000 mi after the guy who owned it before me threw a rod through the block. I don't know the engine type as it has no stamp. I assume that it was replaced with either an F22A1 or F22A4 as the stock intake mani had no bypass valves on it.
Anyways.
Just changed the timing belt/balancer shafts belt and replaced the pulleys associated with them. Had trouble getting it started, turned out i didn't have the PGM ground connected to the body. Originally, I thought I had incorrectly timed it, so I removed the head to check for valve damage. There was no damage, so I polished the bottom of the head and replaced the Head Gasket and the Exhaust Mani gasket. Since I had the intake mani off, I decided to do the F22A6 intake mani swap. I headed over to the junkyard and picked one up for 22 bucks. Also picked up PT6 computer to replace the stock PT3 so I could run the intake manifold valves. Replaced gaskets, installed manifold, ran vacuum lines and wired up IAB box on the bottom of the mani to the computer and dizzy. Then I put everything else back together.
Started the car. First thing I noticed was an unusually high cool idle ~2000 rpm. Allowed to run a bit longer to reach warm idle where it settled at 1100 rpm (still too high). The car then started eratically idling between 1100-2000 rpm. Checked all vacuum connections and they were good. CEL came on shortly afterwards. Pulled codes and got 12 and 14- EGR Lift Valve Circuit malfunction and IACV circuit malfunction.
Eh, EGR valve code was a fluke, the connector on the EGR valve was loose. Fixed.
IACV is still a problem. When it is connected, the car idles erratically between 1100-2000 rpm. When disconnected, the car either sits at a smooth idle around 1200 rpm or jumps quickly between 1100-1200 rpm.
Voltage to IACV is about 14.93 volts
. IACV reads resistance at 0.01 ohms. Voltage at battery is around 14.93 volts
. The IACV is getting coolant. I've tried two different IACVs with no luck.

Very weird stuff going on here. Does anyone have any idea what the problem is?
Thanks,
