Ok, so when I turn my car over sometimes it shuts right back off. I figured that is probably the spark plugs.. Also, when ever I hit boost or go over like 4k Rpm it will sometimes change my idle to 1500 or 2000, and i have to hit boost again to change it back. also, my throttle sticks sometimes.. Anybody have ideas to what it could be? Thanks.

Spray some brake clean in the tb to clean any carbon off the throttle plate

might to adjust the tb plate alittle more. Where the cable attaches to the tb, with the little screw on the bottom

how's the tension of the throttle cable

Do you have a aftermarket or bored tb?

Yea sound like a sticky tb that stays open sometimes.. Where is the rpm at idle?

yea i tried to adjust the screw on the bottom, it doesnt seem to do much.. and the tension on the cable is a little loose.. its a stock tb and at idle it differs. its supposed to be right around 9-1100 but sometimes itll go down to like 600 or all the way to 2000.

Is your boost where it's suppose to be at? Might have a vacuum leak or your iac is dirty or bad try taking the iac off and cleaning it

yea the boost is fine, staying at 14 and 19 the whole time.. and i just replaced the iac last year.. ill take it off today and check it out and look for leaks on the vaccum lines

It's something to do with your tb maybe you have to adjust the screw that controls how much air goes in at idle (do t kno what it's called) lol
