my 93 hatchback once gets warm the idle surges.

I cleaned out the FITV and tightened that thing in it.

That helped make it run a lil better.

But what else can I look at.


The hose that connects to the fitv, there are 2 black metal looking hose connectors things, the fitv hose runs onto them, then there is 2 open ends on on hte black metal thing.

 

IAC on back of intake manifold it has two hoses that runs into it as well. Try carb cleaner and if it still does it get a new one. Are there any CEL's?

 

nope no cel's

 

i took off the IACV there is no screen its torn out.

It doesnt start surging until I start drivin. At idle it idles fine
