Hmmm. On GM products, you open the fuse panel, then turn on the ignition
switch, then remove the CPU fuse. Leave it removed for 20 seconds, turn
off the ignition and reinsert the fuse. GM computers are 'learning'
computers, so what you get is back to basics, where the CPU is in learning
mode and you drive it for a mile or two and let it learn how you drive.

I had to do this several times on the Z28 while in California, as I was
getting a O2 sensor code (check engine light). Come to find out that it
was the gasoline I was using, so I went to a different brand and the codes
stopped appearing as often. They've never returned while here in Texas.

That must be a Chrysler thing. GM computers are wiped clean with a reset,
history and codes included.

That's cool.

Yeah, I don't think my Suburban gets that kind of mileage. My Silverado
gets around 22 max highway in OD, 15 around town w/4.8L and only using 3rd
(1:1) gear.

The suburban is pretty good on fuel, but it's a 1989, before OBD 1 even.

A lot of people do. Around here you see a lot of them.
