Good to hear. Turns out, I had a Diablo tube on mine at the time. I had messed with throttle boost, shift pressures and disabled AFM. It was shifting so hard with the misfire code, I reset back to factory tune and then only disabled AFM. Truck has driven great since with no issues as that reset cleared the trouble code. I did buy plugs and wires since I am coming up on 100k miles anyway and I am getting them replaced in the coming weeks.

Truck looks great. I currently have the RC leveling kit on my 2015 Silverado 2WD with 275/60R20 BFG KO2s. I want to go up to the 275/65. Do you have any rubbing with these tires? I'm just looking for a little extra height without having to go with a complete lift kit. Thanks!

Any update on this issue? I am getting the same code and behavior on my 2015 at 90k miles.

Thanks for the link!

I currently have the RC 2.5 inch leveling kit on my 2015 Silverado 2WD on all stock shocks. I am looking to replace all shocks with Bilstein 5100s for the improved ride quality, but I would like a little more ground clearance as well. Just looking for a little more aggressive look and a little more ground clearance for putting around the hunting property, no major off-road stuff with 2WD of course. I think the RC 3.5 inch suspension lift with UCA would give me the look and clearance I want, but I've read several people ripping that off and going with Bilstein due to the ride quality. I'm torn because it looks like I don't need to combine RC spacers with Bilstein shocks. Any suggestions on which route to go? I'm currently running 275/60/20 BFG KO2, but I would like to go up to 285/60/20 when the time comes.

On my 2015 Silverado Crew Cab 2WD, I currently have the RC 2.5 inch spacer leveling kit with all stock shocks. I am wanting to replace all 4 shocks with Bilstein 5100s. Does anyone have experience combining these shocks with the spacers from RC? I would also like a little more ground clearance. Nothing too crazy, just a little more aggressive look than the stock 2WD height with a leveling kit. Trying to decide if I take the spacers out and go with the RC 3.5 inch suspension lift with upper control arms, remove the spacers and go with Bilstein 5100 on the highest setting all around, or simply replace all shocks with 5100 and keep the spacers up front. Just trying to figure out what will get me the look I want and also be the most mechanically sound so I don't cause any weird issues with ball joints, etc. Any help would be awesome. Thanks!

I had an appointment today to get the pump replaced. The work is going to be covered however, the pump is on back-order with no known lead time. They also deemed my vehicle "unsafe" to drive yet GM will not pay for a rental in the meantime. Gotta love GM!!

I am having this same issue on my 2015 Silverado Crew Cab. Would anyone think the vacuum pump would be covered under powertrain warranty?
