Strange part throttle laziness, WOT is great Stock '04 LQ4 6.0 with a Wait4mePerformance tune and LT headers.
When I am driving normally under part throttle, sometimes the car feels lazy. It just seems like it should have more power under part throttle. Also, lets say I am at 50% throttle and its feeling lazy, sometimes it will just come alive without any further throttle. Its hard to explain, but something is intermittent/flaky here.
WOT is great! No issues. I just replaced the O2's as they were fried. I verified that its going into closed loop and my STFT's and LTFT's look fine to me.(Thats not necessarily saying much as im still learning this stuff)
I am starting to question the MAF or MAP possibly...the only basis for this is that they are junkyard units, thats all.
I have attached a HPTuners log file if any cares to take a gander at it. Near the end the LTFT's start going out of wack, but I believe thats because the O2's are cooling down and its falling out of closed loop.
Any help or clues are greatly appreciated!
