I started an engine swap in May. I am finally finished.

My engine upon ignition starts and runs up to 2000 rpm then idles smooth for about a minute then the idle drops to about 1000, 750, 500 then dies off.
at the fist start of the engine my friend and I had the 3&4 plug wires reversed. So he thought the valves were set incorrectly and changed the valve settings. I then found and corrected the wiring problem. We reset the valves to the H23 tolerances and the engine runs as stated above. Any Ideas?

Also, does anyone have the specs\settings for the intake and exhaust valves. I have been using the manual for the H23 as a guide and I think I am seeing a variance in the valve settings.

Background 94 Honda Accord 2door automatic. I am using a h22 automatic tranny. (too short on funds to finish the manual changeover right now.) I am using the the stock 94 Accord ECU(POA), the prelude power steering pump, and alternator.

Thanks in advance

I would remove the IACV and inspect and clean it. If the vacuum fluctuates after it warms up, most of the time the IACV is clogged up and needs cleaned.

Thanks for the tip. I will give it a try.
