20*F here not looking forward to doing that she can drive the BMW for a wile…

I have a broken exhaust bolt on that side (one on the other side too) and wondering if this is the cause. I also have the AFM/DOD tuned out of the ECM but nothing else was messed with…

I have a couple broken exhaust manifold bolts. One on each side. The bolt head is 13mm on all of them. I see at the salvage yard about 95% are 10mm bolt heads. Do you think mine have been changed at some point or is it what ever GM used at the time. Thanks…

Anyone have any experience in P219A engine code. It pops up every once in a wile.

Send your ECM to Brendan at LT1swap.com and for 50 bux he will disable your AFM/DOD. I just had mine done and it never goes into V4

My 2011 Sierra (LC9) is the only American vehicle in my fleet. I use Castrol 0W40 European formula in all my other vehicles. does anyone see an issue with running this oil in the Sierra….

Nice catch…

Great, thanks…

I’m wanting a spare key for my 2011 GMC Sierra. can this be made at a local hardware store or will it need to be done at the dealer. thanks for the help…

Remove electrical connector at fuel pump. measure resistance between two small wires coming from module. if it shows 0 ohms the sender circuit is “open” and you broke something when removing/installing the sensor. I know cuz I did this before, luckily I had the bed off when I did mine and it wasn’t too bad…

Check the fuel tank straps and the round tube above the rear fuel tank

you Sir are my new best friend. This worked perfect. Your help is appreciated. Thank you…

Try it, let us know…

I agree. Ground issue. It’s using the other bulbs ground, that’s why that bulb is lighting up also…
