Alright so i just did a b18c1 swap in my 98 civic lx. but when i start it it will idle about 1800 rpms and then when i will hit the gas it will rev up and go back to about 3k untill i shut the car off. Any ideas what this could be?

 

BUMP.

 

Check for vacuum leaks. If not I would test the AICV and or block off the FAIV under the throttle body.

 

whats the FAIV for?

 

I think he talking about the fast idle valve under the throttle.

 

Took it for a test drive today and it will do one of two things when i come to a red light:

1. It will bounce from 1k to 2k
2. It will idle at about 2600 rpms

Any ideas??? I'm leaning towards a vacuum leak or something to do with the IACV. What do you guys think?
