My B16 swap is idleing at 2000 RPMs what can I do to fix this? thanks

 

its a vacuum leak somewhere did you replace the throttle body? it could be a leak there. or a vacuum hose not connected. spray some carb cleaner or starting fuid around gaskets and fittings and see if the engine sound changes then you will know where it is leaking from

 

maybe your throttle cable is tight. check the slack, and inspect it for pinches

 

i didnt replace the TB I checked the throttle cable no luck there, and the idle adjustment screw is all the way in. thanks

when did it start idling high then? if it isnt those problems, it's got to be something else....... has it always did this, or just happen yesterday on its own, out of the blue?

 

it started when I first started it, i have only had the engine running for a few days

 

there ya go.... vacuum leak somewhere, iacv maybe? fast idle valve? throttle cable? a ton of options. just go through them one by one.

 

ok i got it down, but now it is kinda jumping from about 700 to 1200. any ideas on this? thanks

 

Any codes? Maybe code 14? Sounds like IACV.

Check for vaccum leak. I had a busted PCV valve and it was idling crazy for a while

 

vacuum leak.

 

no codes, ill check vacume hoses. thanks
