I used my new tech2 to keep the throttle open so I can clean the gunk that was sticking up the throttle blade. Also found some body codes, one of which I will have to keep my eye on. It was part of the HVAC and an airflow sensor. Also replaced the drivers seatback a/c and heater blower, because it wasn't working as good as the new seat bottom I replaced recently.

what were the hvac codes? if you run the calibration and then check for open codes if there is something wrong it will tell you the code

Air control sensor 9, or something like that. I cleared it and will see if it comes back. As far as I know, it's been working as it's supposed to

There are several small temp sensors inside the air ducts that monitor the air temperature & control the actuators in conjunction with the external sensors in the headliner (the ones that look like little microphones) when set to automatic mode. fun stuff I had a crash course lol you have to pull panels off to access them but there easy to test if one fails. you just connect a meter to the pins and then hit the sensor with a hair dryer and watch to see if the ohm's change or not.

Ordered some 22" black snowflakes from OEWheel! Already have the tires and TPMS sensors here waiting. Hope to have pics up sometime next week.

Finished the Wilwoods and re- bent the hardlines for the Swagelok fittings so no more air leaks on The Machine.

looks good, you must be missing the rain somehow? we are about 2 days into a solid week of rain.

First day of sun in a week and a half. Looks good for the next week though.

Good idea using the Tech2 to hold the throttle open while you clean it. It's otherwise a pain holding it open with one hand and cleaning with the other.

Under what menus did you find this?
