Weird rich issue fixed by reset
So I've be running a tune for most of the summer works fine, not perfect. For the last two days it radomly runs crazy rich, if I reset my haltech it goes back to normal.
All of my sensors are reading right, and it occurs at all RPM ranges, temperatures ect. I do not uses closed loop, or idle air control.
What items can be affected by a rolling reset? If it my barometric pressure calibration, what can I do to fix it? Any other ideas?
Could it be my TPS causing the throttle pumps to run all the time but the readings look stable.

Interestingly enough last time I ran my car at the track it did almost the same thing but started running lean at high rpm. I did a rolling reset just like you and it went away. I was going to post a video of the problem but have been real busy.
I run a E6K and I thought it was a baro correction issue too. I checked the Haltech map and it showed the baro correction "on" but when I looked at the actual baro correction map, it was flat. I turned the baro correction to "off" but the problem still recurred. If I turned the car off then on, it would go away!
Seems like we got similar problems.

Checked stuff no smoking gun
I pulled my TPS and IAC and check them today
The TPS is a ford style 3 wire, measures at 500 ohms closed like it should, reads good on gauge page 0% closed and 100% full throttle nice responsive sweep.
I don't run my IAC because my car idles better without it but checked it any way. Both coils AB and CD have 50 ohms as they should.
I think it’s either my baro on the fritz or something I haven't thought of yet.
Anybody have any ideas?
