I have a 92 prelude with with the f22b jdm engine swap and im experiencing some problems. The swap was done awhile ago and its been running fine but recently when im driving and i leave my car in gear and take my foot of teh gas my car will like pull back adn forth adn then when i take it out of gear it will idle down to like 2 grand reall slow and then sit at 2 grand for like 10 seconds and then idle down to normal. Anyone with any ideas of what it may be please let me know.

Thanks

 

1. maybe vacuum leak
2. did you mess with the tps sensor? if you did
you gotta adjust the voltage on the
sensor...

 

yes i had to put in a new tps sensor. how do i adjust the voltage?
