[QUOTE="Eneme, post: 15948329, member: 182285"] New update! So replaced injectors(needed new ones anyways as after all this gets perfectly sorted im getting a procharger setup installed), spark plugs, and coils. After getting a new tune from BAMA and uploading it, the car seemed to drive fine for awhile (like before) but has slowly been getting back to the problem it had before of running rough at cruising on freeway. However, NO CELs atm. When I noticed the car started getting its weird sporadic surging again, I started looking at the short/long term fuel trim on both banks and am noticing that when cruising, both banks are never near each other (both are off anywhere from .2-.4, ex: bank 1 reads like .85, bank 2 reads 1.2 for long and short reads .95 bank 1 and .75 bank 2). But when i decide to give it a little more throttle then cruising or even get on it a bit, everything clears up to damn near perfect with both banks reading similar readings. Suspecting maybe one of the bank 2 sensors is on the fritz even though i replaced them less than 2 years ago when i did long tubes. [/QUOTE]
