hello guys ,
So I have been dealing with vacuum leaks for a while LTFT high both -/+ so i TOOK care of the following items :
(vacuum system re-done al fixed ) , leaky AOS (replaced now ), new FPR , new upstream 02 sensors both banks , new spark plugs , new MAF sensor , bank 1 intake gaskets replaced , oil fill tube replaced
several smoke test - last test no more leaks as of now.
I m down to the "evap purge valve" - read somewhere that maybe staying open causing air/fuel mixture issues !!!!!
last night got my car running after a while seems to idle and run pretty good however bank 1 LTFT - 13 bank 2 LTFT -14 WTF....
both banks upstream sensor voltage fluctuating pretty good , I m afraid soon or later MIL will come back and emission components 2 of still not completed test so waiting for them to be completed so I can the inspection..
help a brother out here what else ?
