Hey guys...just got my s4 FC TII! Man tha thing pulls when its spooled! Its got a few mods here and there.
I'm sure I'll have TONNES of questions for you guys in the future.
My question is that it has a bit of a lumpy idle sometimes,is there anyway to adjust this?

 

Is the idle problem only when warming up? Or all the time? If i had to guess it needs a TPS adjustment. Not very hard to do. all you need is a flat head screwdriver and a multimeter....Check the search function for exact directions.

 

it just happens SOMETIMES at idle stopped at a light or something

 

YEah you need to adjust your tps..(throttle position sensor)
It goes like this "rrr..rrrrrr.rrrr..rrrrrrr.rrr.rrrrr"

Bounces from say 750 rpm's to 1500rpm's, right.. if so TPS is the culprit...

 

lol...thats exactly it...thanx!

 

Also asking how do i get my factory alarm to work...I have a Greddy Auto Timer if that has anything to do with it.
