I have an 01 accord that I swapped a F20B into but the only thing is that when I start it up it shoots up to 3000 rpm and stays there... If anyone can help it would be greatly appreciated I need to get my car back on the road because I have a baby on the way!!

I pulled my codes and I'm reading 4 different ones... I got the codes from 6thgenaccord.com

3 - Map circuit high or low input
7 - tps
14 - ics malfunction, iacv failure
41 - front o2 sensor failor

I have...
Checked vacuum leaks
Cleaned IACV
Replaced tps
Replaced map

I don't have the cat back exhaust connected because I have to order new piping because of the New England rust but that shouldn't make a difference...

 

Just checked the voltage to the power and signal wire for the tps and both are reading 5.2v
