So I had a bully dog tuner for my truck and haven't had it plugged in since I got a new engine installed a few years back. Found it today and found someone who would buy it. Contacted bully dog and found out that I would have to change my tuning to "stock" to be able to unlock the device so the guy could buy it from me. I told them that my truck was already stock and they said that I just needed to run the stock tune to be able to unlock it. So I did that and it cut my engine power and turned off ABS and Stabilitrak. Cant go over 25mph, truck shakes, sounds weird. I have no idea what to do and their customer service is closed for the night. I have work in the morning, any suggestions?
Hi! In April, my Yukon was throwing codes P0172 P0175. Local GMC dealer in Louisiana "fixed", by replacing some sensor. Traveled to PA, codes came back on. Local GMC dealer fixed by replacing BCM, body control module in June. Now my check engine light is back on! Power train Warranty ran out 2-3 weeks ago. Also had extended warranty, which also ran out at 5 years, which was Sept. Code onstar says its throwing now is P0430, all of the codes from I can find are related to exhaust system. My question is are these 3 codes related??? Could this be something they will have to fix under warranty, given it's related and has been worked on several times?
If not, what does this mean? Catalytic converter bad? Help! My husband is being laid off in the next week. So, obviously finances are tight. Yes, obviously itll be fixed regardless, just trying to plan and cut back elsewhere if needed. This has been a great vehicle! As luck has it, trouble starts when warranty runs out.
Really wanting to trade, but waiting on new body

I replaced the Electronic Brake Control Module on my 04 Yukon with a new one so then I took my Yukon in to the dealership to have the EBCM module programmed and an hour and half later they say they couldn’t program it because there was not an option in their MDI scan tool list for it to be programmed all though it showed codes for needing it done. I asked them if they could just use the Tech2 and get it done but apparently they don’t use them or won’t use them any more? Anyone ever hear of this? Any GM techs here have any ideas how to get this taken care of. I don’t feel like spending tons of money so a tech can sit there and try all day and I’m tired of looking at all the dash lights and hearing annoying chimes at startup. Thanks. 04 Yukon with JL4 active brake control.
I found it from amazon
Launch CReader 3001,here shows $24.99 https://www.amazon.com/dp/B07CH4D68Q/
Launch Launch X431 DIAGUN IV,here shows $549 https://www.amazon.com/dp/B072FHLYRY/
That price is big difference,how to choose it ?
I have a 2012 silverado and my check engine light keeps coming off and on. The codes read are
c0900- device 1 voltage high(history)
c0899- device 1 voltage low(history)
p0300- multiple misfire detected (History Mil)
p0301- cylinder 1 misfire detected (confirmed)
there is a slight rough idle on the truck, and I think that my gas mileage has decreased slightly
Does anyone have any idea what my problem could be before I take it to a shop, or start replacing parts
