ULTIMATE B16A ENGINE PROBLEM PLZ HELP

ok here is the run down...
i have a 96 civic ek, i did an engine swap and put in a b16a4 with the corresponding ecu.
now my problem is that when the car is cold it will idle at about 1200rpm, as i drive along as i start slowing down to stop when i put the clutch it the idle goes up to 2000rpm or higher then once the car is completely stoped it will slowly drop to around 1500rpm. it will keep doing this even after the car has warmed up.
i hav found that once the car has warmed right up if i turn the car off then back on it will run fine.
can anyone plz help me figure out what the cause of this problem is :(
things that have been checked:
*throttle body
*vaccume leaks
*iacv
*ecu
if u can help me fix this problem i will forever be ur servent
HELP ME ITS DRIVIN ME CRAZY!!

have you tried checking your throttle cable locknut? that probably should've been done with the throttle body inspection, but just in case it wasn't. I had a similar problem with my civic and it was the locknut getting jammed when I was driving.

have you tried cleaning your iacv?

What do you mean by "checking"? Visual inspections aren't the best way to rule something out. Clean your IACV out.

And what is this mysterious b16a4? I've never heard of this engine, and I've been around Hondas for over 4 years.
