High idle after frontmount

[bjmauck]

I installed a PR front mount and short route kit after hitting a dog and denting my small greddy kit. My car was running hotter then normal after install. I Installed a PR radiator and 170 t stat and made a piece to go from bumper to radiato support to force more air thru the rad cause I'm thinking its due to the restriction from the frontmount. Car Idles great cold but after driving it will idle around 1500-2000. I can turn the a/c on with heat blowing and the idle comes down after a while. I have the stock cooling fans. Is there a cooling fan controler to solve this or anyone have a solution? Thanks for the help.

At first I was thinking throttle cable since it's only happening when warm, but if sucking the warm out cures it I'm not sure. PR makes that dual shroud fan to go with the aluminum rad

Have you tried properly adjusting the BISS, and not just the half assed method of just screwing it in/out which does next to nothing?

Sometimes after installing a new intercooler you need to adjust it, hell even piping can cause it.

How do you adjust biss?

Double check all ## joints on the intercooler pipein any small air leak could cause this symptom

Why did it take this long for someone to say boost leak? Just reading the title of the thread, the answer is boost leak test.

Even If my wideband reads good at idle?

Yes, your wideband would read fine with a boost leak at idle.
