Ok I just installed my FMIC. But now the car will not stay running unless i have my foot on the gas. I does idle when cold but VERY rough. Once it warms up I have to keep my foot on the gas to keep it running. As soon as i Let off the gas it will die. It is also running Extremely rich. I did manage to get it up to normal op temp and adjusted my TPS (just in case). There are a couple of things not hooked up. The 2 vaccum lines that go into the stock intercooler are caped off. and the hose that goes into the stock IC pipe is not hooked up (ill enclose a pic). Any ideas on what could cause it to be running horrible? Thanks so much.

 

Sounds like a vac leak. That connection probably pulls vacuum. Plug it and see it it gets better. It could also be a loose coupler or something, but it definitely sounds like a vac leak.

 

ill probably have to have the hose in the pic hooked up cause if i plug it the car dies. ill recheck all my couplers again

 

you can't just cap off lines that pull air, you need to ether leave them open or hook them back up to the IC piping by drilling and welding a fitting onto the IC piping.

 

ya i didnt cap that one in the pic. Its still pulling air. The other 2 that hooked up to the side of the oem intercooler i capped off

 

if that good year hose isn't hooked up that is a major leak. that is the BAC valve and helps idle.

 

ya im hping that is whats causeing my idle issue. Im gona go down on wed to the welding shop and see if they can make an adapter on my IC pipe for that hose.
