I just finished helping a buddy swap in a 1994 B18 from HMO. After we got it in, it wouldn't start, but I changed the ignition coil and it finally started.

There's a couple problems however:

1) The idle is really low. Like less than 500 rpm. It started cold at like 1500 like it should but after it warmed up it was waaaay too low, it felt like it was about to die. I turned the idle screw up, and the idle raised when I turned it, but after I was done turning it up, it would go back down after a few seconds. The idle is not surging or anything, just really low.

2) There is a really loud "sucking" noise coming from the throttle body area. I know Honda's with CAI's usually do this, but this was LOUD. When I took off the intake, it was definitely coming from the TB area. It got alot louder the more the idle went up. It sounds like Darth Vader on a constant inhale.

Any suggestions?

 

My buddy had a similar problem. Turned out to be a vacuum leak IIRC.

check the TB gasket.

It's a "new" motor from HMO. I'm pissed that I even have to check things like that. Someone else suggested it was the IACV, which would account for the idle and the sucking noise.

 

that's possible too.

 

BUMP
