Hey Guys,
A friend of mine has a S5 right now that he just got that seems to have a high idle and running pretty rich.

Is this a common problem?

I don't know a lot about FC but I am sure you guys do so any help would be great

His mods are: full racing beat exhaust, mild street port (fresh motor), K&N intake.

If you guys need more specific info just ask and I'll get it from him!

Thanks Justus

 

I want a high idle... hell I want any idle at all :/

Could be a number of things btw. Check tps, it can affect how richly hes running, but considering its a street port, I'm curious if hes running stock fuel delivery? That would hardly seem rich...
