okay here is the thing I fire up the b16a sir2 swap in my EF and well I get the sucker idling from 2000 to 2500 rpms back and forth nothing less then this. I kill it with in seconds not letting it continue. I have no header at the moment.

I had this problem right after I brought it home from the shop with a ls/vtec set up I had before that is gone now. And would figure this swap wouldn't do this. Now could this be wiring, eCU, or sensor related.

I am using the old manifolds(intake/exhaust) from the ls/vtec set up


HELP!!!

I like to drive my car this weekend to the crand opening in Azusa, Ca
Revolution autowerks

 

vacume leak?

 

could be will check over in a bit anything else it could be????

 

sorry not vaccumm leak

anyone else??

 

my friends accord did the same thing afer we swapped in his H22, our problem was an 02 sensor

 

i thought it was that too but have a semi new o2 and nope ain't that

I was told it could be ICAV but I cleaned it and still no good

could it be a leak in the manifold like not bolted up right to the head??

 

does the idle problem go away if you drive it for while ? or does it always do that

 

try the fitv.
Mine does the same I changed the FITV and the IACV and the TB. Told itd probably my ecu. Still have no clue, but hopefully its your fitv....you take the back plate off and screw it back in and then it should work...didn't for me but helped others.

 

haven' t tried driving it yet just sounds way to wack to try to

and will check the fitv

where is that I don't think I got one...


and yeah I can't find the size allen tool for the IACV so screw it all the way in right what can I clean it with carb cleaner or WD40??

 

carb cleaner....fitv is under the tb there is a little plate on the back like half dollar size...take that off then screw in the spring

 

sorry guys I don't have that thing on my set up or Throttle body

I removed it

 

it comes on the tb it is part of the tb..try doing a search for fitv...should be some pics of it

 

i have a aftermarket throttle body and it was removed
during the build

 

a buddys of mine did the same exact thing but only at a full stop and when the car was in neutral and the clutch was engaged. also he had a spoon chipped ecu. and that was the problem

 

found the issue it was the IACV I guess all I did was cleaned it and adjusted the throttle cable and DONE!!!

I guess it was the IACV or the throttle to open


as long as it fixed it right??

 

definitly as long as it works is what counts
