Ive been fighting a lean condition for awhile now and it finally through the po171. LTFT's are at 16.4 but when driving around itll go down to 3 and very depending on mph and where the rpm is at WOT its at zero though. Ive checked my egr tube and vacuum lines with no luck. My car only makes 5 psi on stock pulley but when its about to shift itll hit 6.2psi which is where it was at the beginning. And it has lost some power. Idle doesnt seem very ruff.
 


Possibly but it would be easier to run some seafoam through the vacuum lines and see where it smokes out of
 




I'll try to get pics up. My laptop broke so but I'm trying to get it fixed soon. But if you look by the valvecovers you can see the bolt holes in between the humps. There part of the heads.
 


Mount holes? I know the front pass motor mount bolts to the head, if you have the L67 bracket then those holes will be there but nothing in them. Rear head has the same holes but I forgot what goes into them, some bracket of some sort...
 
Ok thanks them are what I was talking about. Well anyone have any ideas why it keeps leaking? I'm going to try changing it again soon but anyone have an idea on what to look for?
