help i just got this car (90 std hatch d15b1 dpfi) new to the honda game
i though my injectors were bad so i pulled it apart last night
took off the mani throttle body and fuel lines
put it back together after a basic lil clean (wasnt dirty)
replaced fuel lines
now its idling around 3500 i have no idea why please help!!!!

 

did u replace ur IM gasket?

 

no was i supposed to? can i just grab it at autozone? how much are they?

 

if the old one doesn't come off in one piece and is visisbly deteriated then its always a good idea to replace it. It's either idling that high due to an air leak at that gasket, or you have a vacuum feed disconnected.

 

well when i tried to pull the mani off the tb one of the bolts was like stripped and just kept spinning so i couldnt even pull the mani all the way off

 

not the tb when i pulled the lid off the dpfi thing where in intake conects one of those nuts just spun and wouldnt tighten or loosen
but thats the thing my intake hooks up to...idk if thats a big deal cuz in theory couldnt you run with a bare throttle body

 

i made sure all hoses went right back where they were as well

 

bump need help im at work get off at 6 wanna fix it before i leave here

 

youve got a vacuum leak probably from where you took apart the IM i would get all the gaskets from the components you took apart

 

figured it out...just readjusted my whole throttle....no big deal

 

thanks for the help homies
