High idol issue after HSW 78mm palate install...HELP when I first start my car on a cold start, it idles at 300rpm, then stalls...crank it, and it starts, idols around 500 then stalls...everytime, 3rd time is a charm but it takes a good 15 seconds bouncing from 400rpms to 900...then it will idol at 1500 and hang there...
then once its warm, I shut it off, and start it and it idols up to 2k, then slowly makes its way down to 1k then its good to go. It drives normal and idols normal after that initial start and it never did this until after my HSW plate install. It almost acts like there is a VAC leak, but once the car idols down, the idol is good and it doesnt bounce around...
do you guy think it could be my throttle blade needs to be adjusted now? I checked to make sure the throttle cable wasnt pulling on the TB butterfly a little, and thats not the issue. Any Idea's???

The HSW kit comes with a throttle cable extension mount...so it already has it.
My gaskets are good on both sides...I double checked it today and made sure all bolts were tight.
also, I noticed that my TB butterfly is shut all the way, and I have the hole on the TB blade plugged....I had this problem before with it hard starting and wanting to stall and I just adjusted the butterfly by the adjustment screw enough for it to suck a little air.....I am 99.9% sure this is my problem again being as im a MS3 car and enough air on startup is critical.

I did this. Its getting a new street tune/dyno tune from scratch april 17th so it should run MUCH better. Until then, I will adjust my throttle body again.

I wouldn't recommend using the throttle stop to adjust your idle speed etc. You need to keep in mind that if things aren't functioning properly or set properly, adding additional go fast goodies is only going to compound issues. My advice would be stop messing with it and have a tuner adjust it properly to avoid anymore issues.

I was asking why you're running two nitrous solenoids in series like Cam above asked. Looks like it was a dry kit at one point prior?
