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.

Check for vacuum leaks.
Check your crossover for an exhaust leak.
Try cleaning your MAF sensor as well.

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

Is that okay on the motor I've heard seafoam can do more harm than good sometimes

It Won't hurt anything

Anyone have an idea why my uim gasket has a vacuum leak again I just changed i, but its got smoke leaking again.
06-11-2013
Maybe it was bad out of the box?
What brand gasket was it?
06-12-2013
Did you torque the bolts down tight enough? Is the plastic cracked?
06-12-2013
UIM gasket being the SC gasket. Where is it leaking?
06-12-2013
Felpro. And the smoke comes out right below the snout.

Disregard my last post i was thinking l36. Is your LIM ported or stock?
06-13-2013

What's the extra holes for inbetween the valvecover bolts.
06-14-2013
pics?
06-15-2013
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?
