No, Onstar reporting was excellent.

2016HC 5.3. Installed Range AFM Disabler last week, seems to be working as truck stays in V8 Mode. However, I am getting diagnostic reports from the My Chevrolet app now for Engine & transmission, Antilock Brakes, Stabilitrak, Airbag system, and Emission system. There is no Check Engine light. As a Constable, when I am serving a summons, I install the Speed Turtle plug and never had a problem (also an ODB port dongle). Any thoughts? A random spur by the Range? Bob

Just FYI, I also bought these FOBs and the programmer worked 100% https://www.amazon.com/dp/B09FSNX41P?psc=1

I have no relationship with this vendor. I ordered this replacement FOB for my 2016 HC. Amazingly simple, really under 5 minutes. New FOB works perfectly including the OEM remote start. No effect on my other FOB. Plug the programmer into OBD port and done in about 15 seconds. The packaging says good up to 2015, but replies on Amazon indicated it works for later years, I guess they never updated the packaging. $74 for new fob and programmer. Was so amazed, had to post it. https://www.amazon.com/dp/B078XJWCH7?psc=1

Every few months I get a check engine light. OBD reader shows P0700 #07E8. I notice nothing or feel nothing. I have the 8L90 transmission. In a few days the light goes out. Because its a pain to leave truck at dealer for days, I have just been ignoring and continuing on. Any suggestions? 2016 HC. Again, continues to run fine, never had a noticeable problem. Bob

No, runs strong though. I understand what a compression check is, but I dont know how to do it. I assume you need to access the practically inaccessible spark plugs.

Without going to the dealer, I am having some problems finding where to order these letters. I lost the “A” and it bothers me to have a Silver do. Any pointers on where to buy these OEM letters so I can just double side tape the A back? Thanks!

What is the purpose of calibration?

Wicked expensive! How much additional were the lug nuts, TPMS etc…. Did you just bring new tires for them to install on the wheels? What did they hit you for calibration etc…?

I decided that I want to replace my factory chrome rims with black rims of some sort. While researching, I see we need to know the offset, something I never considered. I cant seem to locate what the OEM rims are and order close to the same. Anyone know what that spec is, and maybe a recommendation of some high quality aftermarket rims? Thanks, Bob

Finally someone answered the OP’s (me) actual question!

Well this whole thread is pissing me off. After all the raving about catch cans, and now seeing 1/2 oz of oil in there that would have been directly injected past my valves, everyone seems to be ranting AGAINST their use. WTF is going on? Is it not beneficial to stop this blowby oil from gunking up the intake valves? Bob

In MA, they dont even open hood, all done by OBD, lights check, ball joint check, tire check, wipers check. They might open hood if they suspect after market HIDs or something unusual. Not sure if CC is illegal or not.

Just to verify, I’m not a mechanic. If you plug the intake port (I assume where the catch can output goes) do you also plug the PCV port? What happens to the blow by oil particles that would have ended up in the catch can? Will the truck pass emissions and/or throw codes?
