i cleaned the tb already. i had it off when i did the valve cover gasket. i cleaned inside AND out. i took a wire wheel to the outside just to get the nasty grime off of it, and it was spotless on the inside when i put it back on. the tps pigtail and sensor is brand new as well. just builds boost slow. heres a funny discovery though. i wanted to see how it would run in the cold, so i laid onto the loud pedal for a second, and when i let out i smelled something burning. it smelled kinda like oil. long story short, i pulled into a well lit gas station and sure as shit, large oil leak. my expensive blue rubber valve cover gasket was BLOW OUT COMPLETELY on the front half of the valve cover on the passenger side. im not a genius, but this tells me i may have a bad pcv? which may also be causing my slow turbo spool? anyone?
