I have a 01 ls with 140k original engine.timing belt and everything else just done like 4 months ago. Everything in the engine is fine..i hope... but after i start the car from cold. it idles at like 13 to 15 hundred..then warms up and it some times idles at 800 but sometimes it dips down to and between 400 and like 550..any ideas on what this might be.like i said the problem is somewhat but not totally intermittent.thanks

 

Check the intake manifold for leaks and clean you iacv

 

is there an fitv on a manual tranny

 

I have a manual tranny, and have a fitv. It's located directly underneath the throttle body. There will be some coolant hoses connected to it.

 

i took off what i believe is the iacv. located directly behind the intake manifold, mounted to the manifold after the tb. 2 12mm bolts 2 coolant lines i assume in and out,and 2 phillips head screws.i pulled it off saw the screen on one of the ports had alot of residue,scraped the residue, the 2 phillips head screws will not come off without stripping them. Ill probably get a junk yard one and see if i can get its screws off and do that. if i pnp my intake manifold. how long can i run it until i can afford to pnp the head?

 

Yes, the IACV is directly on the back of the Intake Manifold, and the FITV is located under the throttle body on the left underside of the manifold.

I would wait on the pNp for your intake manifold until you have the funds to do the same with your head. Your really not going to gain much with out the supporting modifications, and a decent tune. To me it would be worthless to do so.

No, you dont have one, they came on older integras

 

I was under the assumption they all were equipped with one. I own a 1994 model so that would explain things.

 

i drove the teg for aprox. 45 minutes after warm up and the car idles at 500. how can i check to make sure that my gauge is correct. is there an rpm laser similar to a radar gun.also is a complete engine with accessories b18b for 200 worth it...in need of rebuild.
