So I have been out of town the last couple weeks so I haven't had a chance to do anything with the car, but as expected, the car has been running normal for the wife. Like I said in the original post, this issue only pops up ever couple months, it will do it once, and it is fine...
Last night I took her car for a drive (not planning on testing) and noticed something odd. When I was merging onto the freeway, I got on it pretty good, and to my amazement, I look in the rear view mirror and see that I just hazed out the freeway behind me...
I pulled back off the freeway, opened up torque and just had it set to watch long and short term fuel trims (didn't take the time to load up other views). Did a couple more WOT runs on the way home and what I saw was that at WOT everything BUT Long Term Bank 1 would go to 0% or close to, while LT Bank 1 stayed at about 4%. Is that odd? Once cruising for a while, both LT trims would return to "normal", but Bank 1 would stay 2-3% higher than Bank 2.
Like I said, I didn't watch anything else, so I don't know what AFR was doing or if there was excessive knock detected, but I did check and it was showing any misfires or anything.
So, my concern is the hazing under heavy load. I don't know if it was a fuel haze, or an oil haze, ie turbo seals. If it was an issue with the turbo seals, my gut would tell me it would do it under any throttle (at least that's what it did in my diesel truck). Any ideas on the haze? I should add the car is stock, and has been since the new shortblock was installed.
I'll do some more testing when I get back from Chicago next week and load up a whole bunch of things on Torque and/or FORscan. I'll watch fuel trims short and long, AFR, knock counts, knock retard, misfire count, cam VCT errors(not sure if I remember seeing that in either program), anything else I should monitor?
