Now that you have all that retired free time it'll be fixed shortly, right? ;)
It will be taken care of as soon as the part gets here. :D
Although it looks like a little bit of a PIA since it is way up under the dash.
But there are quite a few good YT vids out there on how to do it right.
Even if the Yukon throws an error after I replace it, I can recalibrate the steering angle sensor with my scan tool.

But, it is hilarious that I thought I would have tons of time once I retired.
I have been so busy this week that I am wondering how I ever got anything done when I had to go to work every day. :confused:

it's so harsh on everything plastic, inside stuff, the headlights and all. just baking in an oven.


I try to get everything done before 11am. if you see me out of the office after noon something very bad has happened lol. it isn't fit for man or beast out there in that sun.

Just ordered a new steering position sensor, genuine GM.
Mine went out and now the traction control and stabilitrak is erroring out.
Mine was out for a long time. Plugged a new one in but didn’t mechanically install it. It takes care of one error, but not the other. When I finally replaced it properly, I was surprised how quickly it took.

do you have over temp protection for the cats turned off in the tune? cause it really shouldn't matter how hard you drive the car. cat temp and life has to do with heat and their heat is controlled by the a/f. if cats can survive track days and race cars, you really shouldn't be able to hurt them unless you run leaded fuels?

cot you have to turn off while tuning, but if you're going to have them on the car it should be enabled after tuning. lot of tuners don't because they feel it's not needed and most high hp sports cars aren't driven daily and or only a few 1/4mile hits at a time. but they can melt them at their first track day if the tuner left it disabled.

My washer reservoir ran dry yesterday, and today I filled the reservoir with a freshly-opened gallon of juice. That's a pretty mundane thing to post in this thread, huh?

What I learned, though, is that the "dry to brimming" volume is about 4 oz shy of a gallon, so I'm stuck holding onto a not-quite-empty container. Grr...

my '03 Silverados has like 280 something on it that I sold to my sister. It has original cats and I drove the s*** out of that one
Why do you have aftermarket cats? Did it come with them? Did your OE cats crap out and you had them replaced with these? Were they stolen?

A rear wiper line "Purge" may give you enough room to take that.

the oem one's lasted me about 3 years from when I bought it, I then had them replaced with some magnaflows and those lasted me about 2 years, then I had these "catco" put on and they don't last a year. they run around $650 each, the magnaflows were $650 but have since doubled in price and are now $1200 each. Oem is around $4000+ for a "set" plus a core charge.
I have a history of making cat's go bad, they don't melt they just stop working. I don't even know how many I replaced on my 00 (several)
wierd thing is it only happens on my suv's, pickups seem to be setup different I guess
these are my options aside from a catco, has to be carb compliant they get under there and check the numbers
