just installed a n2o wet kit on my z. i used a msd window switch, fpss, relay, wired it up by instructions... and it works flawless... i drilled into the bellows to place the nozzle and put the wot switch on the tb. it DOES NOT stick. but when i'm driving (normal conditions and gettin on it) sometimes the idle sticks around 1000-2000 rpms when i let outta the throttle. i can "pat" the pedal and it will go back to normal (750 rpm's). why is that. there's no vaccum leaks and it's annoying as hell! any help is greatly appreciated.

 

Sounds Like A Sticking Tb.... Or Mabye Something Worng With Your Tps .. Id Get It Logged And See Whats Going On When It Happens ...

I Just Had The Eaxct Same Problem With My 90mm Tb Where The Tb Would Stick Open About 5% Every Now And Then.. It Never Happened When I Was Looking For It But One Time I Was Luckey Enough To Be Loggin The Car When It Happened And Could See The Tps Sensor Recording 5%
