So I have a 94 eg just swap a b16a. It's running an the gauge gets to running temp but the lower hose doesn't get warm like the upper on an the fan won't turn on.

Fan work, have a good groud. Everything work before I did my swap.

Any ideas on what to do on this problem

 

Air in system.

 

I open up the air bleeder where the top hose goes into the head

 

^x2
Bleed the cooling system

 

So I put the heater on hot to open up the heater core an I got the lower hose to get warm an the fan kick in. But I still have a idle that goes up an down. Any ideas why the ba idle now

 

FITV

 

Still? This is the very first time you mentioned it.

 

^ thats what I was thinking...but kind of confusing. He says still has idle that goes up and down and why the bad idle now?

 

Oh yeah I forgot to mention that

 

buddy of mine JUST had this issues like 4 hours ago, he spend 2 hours bleeding the system untill all the air was out.

 

Your bad idle might be the throttlebody wire thingy, dont remember what the name of it is.

 

Very helpful you are lol... iacv (idle air control valve)

When I got my motor from hmo I pulled the iacv off and it was completely packed full of carbon lol

 

so should i continue to bleed the system and clean out the iacv?
