Hi all,

I did a search on this but didnt find anything and to tell you the truth im not exactly sure how to search for my exact issue. So here it goes, sometimes (but not extremely often) after I have boosted hard in 2nd or 3rd gear and let off my rpms stay up high. Kind of like my throttle is stuck open or something and i have to upshift and give it gas to get them to drop. Has anyone else experience this? It seems to me like my BOV isnt opening and the boost levels are keeping the throttle plate open even though my boost gauge doesnt show pressure? Is there something i should be worried about or checking? Any suggestions would be great

Thank
Troy

happens to me all the time, and many other evo members. not sure how to fix it or why it happens, it does seem like the TB doesnt close all the way

 

Ya mine does it also try and put the clutch in again when it hangs the rpms will drop.there is a pretty good size post called throttle hang that has more info in it.

 

im on my second evo now... im only 20 haha... but after i put in a new clutch.. i started to notice it on my first one.. and it didnt feel right when brake boosting either.. kinda felt like it wasnt makin the power it should have doin it.. but the clutch felt good.. chirped tires in a stock car... just clutch 255 fuel pump boost contoler and k&n cone

 

Its the ICV sticking (was in mt case, exactly the same symptoms), take it out clean it and stick i back in see if it helps, if not get a new one.

I had the same problem before and after changing the ECU, threw out old ICV installed new one, problem solved

 

same thing, whats the ICV
