You were lean so the timing could be higher w/o knock. I thought the LTFT were tested better under normal cruise. Isn't PE for WOT?

the ecm is still adding fuel, BUT not as bad as before.

im used to getting toe in knock. sudden shock to the system, nothing major really. contrary to popular belief, knock isn't a bad thing, well im small numbers it isn't.

all my dsm's had the toe in knock, but then it would quickly go away. like above.

roll into the gas no knock, stab it, knock

So, my lifetime gas milage has dropped to 19.7 with 20K miles in 6 months, it's obvious I do a lot of highway driving.

Is it safe to say my factory programming sucks, literally?

I thought OBDII was supposed to be smart. This car has never hit the factory 28 mpg average, and my past W-Body's all averaged 24.5 mpg lifetime.

What gives?

mine comes from being leaner then **** 810-825 mv at wot kinda kills the power. runnin about 15.0:1 on normal driving helps out a bunch on cruising, not so much on power.

I had that problem last summer also. I had to get the LTFT's down in the negatives to get rid of most of it. Course I never had a LTFT at 9 at WOTHere is one of my logs at the same spot as yours.

Area, Didn't you relocate the IAT? Have you tried to put it back and then check the LTFT?
