92 prelude swap

[RandyKulp]

i just swaped in an h22a1, becausethe h23 went south. it runs great except for at idle. it serges from 1000 rpm to 1600 rpm. i repaced the tp sensor, and the iac motor, no better. does anybody have any ideas.

map sensor?

try bleeding your coolant system....i had the same problem and it fixed it!

adjust the FITV on the bottom of the throttle body

Most likely either air in the coolant system or the FITV like people mentioned already..
