Well tomorrow I SHOULD get my intake tract tested, but as everything has been going down who knows

Figured I would throw some info and two logs I took today for the hell of it. Also will put the fact out there that this week I have been running on Sunoco gas from a busy area rather than Citgo gas I get from down the street.

A/F learning looks like its changing, I was cruising no throttle at -.78 then slowly it went to +.78 then tonight it was cruising at +1.56. I will note that I have been not hesitating to take the car to boost for the past couple days as I had been the last couple of weeks which most likely will change Learning ETC.

Here are the A/F Learning Numbers after driving 1 Hour 20 Mins from work this afternoon.

1:-3.12 (-5.47/0.78)
A:-3.40 (-3.40/-3.40)
B:1.00 (1.00/1.00)
C: -5.20 (-5.20/-5.20)

Here are the A/F Learning Numbers after a trip in to town in stop and go traffic tonight.

1:-5.47 (-5.47/1.56)
A: -5.80(-5.80/-5.80)
B:1.30 (1.30/1.30)
C: -5.30 (-5.30/-5.30)

@50 Degrees F Moist Foggy Morning
Log from this A.M.

@71 Degrees F Dry Clear Evening (wife was with me had to cut it short to avoid the wrath)
Log from this P.M.

I know the A/F learning values are learned over periods of time and you generally monitor them over the course of 1+ tanks of gas. I simply am including this data just to be as thorough as possible with this entire post so I have it for my own records.

I see mostly slight knocks here and there within the -1.4 area with the most extreme case being a -5.6 that I saw while accelerating up a larger hill earlier today.

Some Fine Knock Learning periodically happens during acceleration in second gear as well. Other than all of this I am not noticing any loss of power and the car is not throwing any check engine light.

Perhaps this is a case where I got some bad gas from a station and need to chalk it up to learning or I will find out tomorrow that I have an intake tract leak.
