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…

I love this comment… you are also commenting on a four year old thread…. and now so am I…

Thought I’d throw this out for you guys. I sent my ECM out to get the AFM/DOD delete. All went good with that. for what ever reason I decided to remove and clean all the carbon from the throttle body after success of new V8 power. ( it was horrible from almost 200,000 miles). After reinstalling and starting the engine the idle would never be the same, it was all over the place from 800-3000 with no rhyme or reason for a steady idle even after many idle relearn procedures, battery disconnects and test drives. I came across a video where the guy says to not clean the throttle body or you will have the exact issues I just described. I took the truck to a buddy who has a TECH 2 scan tool and 30 seconds later the truck idled perfect and better than ever. From what I been reading the throttle body gets carbon build up over time and the ECM compensates for this carbon, in my case 200K miles worth. After cleaning all that carbon out the throttle blade still remains in its “learned” position and this causes the crazy high idle. So, just an FYI if you decide to clean the carbon from the TB be prepared to have to deal with this. My guy charged me $40 to do the idle reset, the dealer where he works at would of been just over $100 ….

I had same issue. Both of those lines go up further and disconnect. the fuel supply into a steel fuel line and the bigger into a vent/canister of some sort. I was able to get mine out with a few choice words and needle nose pliers. They make repair kits for the fuel tank support/crossmember. A cheap eBay no name fuel pump module is still working. I removed the bed for access to all this…

If the bell housing comes off the “new” transmission and it’s missing the very top bolt and a smaller input shaft, you have a 4.3L V6 transmission

very true. If it only does this for a few minutes in the AM I would bet it’s this…

I swapped in a 25797978 navigation unit into my 2011 Sierra everything works except Bluetooth. When I hold the phone button down I get a “beep” not a “ready” like my factory radio did. I say “Bluetooth, pair, phone” all this comes back as “not recognized” I can however say “radio help” and get a response. My guess it the unit I got is from an earlier (07-08) truck and Bluetooth wasn’t an option until 09. Can my older unit be flashed with a TECH 2 for Bluetooth. Any help on this is appreciated…
