idle problem...

[Boosted19]

ALright I'm really frustarated at the moment.. Firts nice day of the year hear. Its pretty warm out in the 70's. Im driving in traffic. (slow stop and go) And then my ilde goes up to about 2000 and wont go down. Then my clutch MC starts to pump up so it feels like shit. Ive been messing with my BISS before because if I would go to neutral when Im on the higway it would stall. Not fun. Then I noticed my idle adj. srew was only on by a couple of treads so I put that where it was and then try to put the BISS back to where it was. It was fine for a few days then Today is when it went up. Shut the car off. Then it was fine. Then I turned the BISS in a little to lower the idle. Then Im on my way home and it goes back up again. Im also having a problem on cold days if I run about 17 pounds. I hit like fuel cut it feels like. Im sure this is all related. Other then the Pump up. I have to do another boost leak test so mabye that will tell. Any ideas so far?

well i spent sometime today adjustaing the BISS and idle screww. Got it to idle ok but then it startes to idle high again after a couple of mins of driving. Only up to about 1500 now is what I got it to from adj. for a while. but it idles at 1000 then sometimes it goes to like 600 then when I rev it and have it in neutral it almost stalls... I give up for now. Im tired of fooling with it. Any ideas?

I have this problem too.. When the weather starts getting warm and my engine starts getting hot it starts to idle from 1500-3000rpm and usualy i can just hit the gas peddle really fast and it will come down to regular idleing. Ive changed my tps, throttle body, ecu, o2 sensors.. tried to adjust the BISS but this all doesnt do anything... i suspect it has something to do with the eat since it only happens on warm days when i get stuck in traffic and there is less air going to the engine. Ive checked my engine fan to make sure it was coming on and it is.. the engine isnt overheating it just idles high and i cant find the reason to it. Someone please help
