ok turbo spools,runs ok but a little slugish.when i idle after a quick run the idle goes up to 1.2k at full stop. it just stays at 1.2 it doesnt go up or down,but when i restart the car it idles normaly. strange...

 

vacuum leak.

 

small vacuum leak.
hoses heat up after run. air leaks....

platinum.

 

ill check the lines

 

Ok I have the same problem but my idle does go back down, after a moment, nothing really weird cuz it doesnt fluctuate it just stops at 1200 then slowly creeps down another 200-300 rpms. The strange thing is that it always idles higher when I have less(close to none) fuel in the tank, I just assumed that was because of air in the fuel line and the fact I have 990 injectors.

 

boost gauge line had a kink,turned into a leak. but i think its the map sensor being stupid
