  1. Finally got this fixed on my truck. Fuel injectors. My truck threw a p050d code and misfire code. Turns out two injectors needed to be replaced. No more tick!
  2. Madsen, Did this help with the tick/fluttering? I understand it may block the noise but have you had any luck isolating where the noise comes from? My truck has done it for the life of it and I'm at 50,000 miles. Bothers the piss out of me as well but I've learned to just live with it.
  3. Guys, -UPDATE- I dropped my truck off at the dealership because the noise was the worst it has ever been. Well as I'm on my way to the dealership of the course it goes away and they can't replicate it. I did take a video when it was doing it so I had that to show them. Well anyways they reported it to GM and asked what they should do and it turns out that GM has created a service bulletin 6 weeks ago looking into a fix. Their engineers are currently looking into all options. They claim it is related to the Active Fuel Management. Which in turn is affecting the transmission, drive quality, and everything else that is tied in with fuel delivery ect. So, fingers crossed it gets resolved soon. The dealer is going to contact me when they come up with a fix. They told me the bulletin was for 2017 and 2018 models of Sierra/Silverados. It was for the V6 and both V8. I was to the point where I was going to start test driving Fords. I guess I will wait a month or so.
  4. Is there a valve or solenoid used for the Active Fuel Management system? It seem that it is something with that since it is related to being in V4 and V8 mode. I've also noticed when the tick is loudest the truck bogs and surges. When the tick isn't present the truck runs smoother. It seems like it all has to do with the fuel delivery.
  5. Fuel feed line did nothing to fix them problem....
  6. Did you ever figure out the footwell ticking issue?

      I have had no luck finding what causes the noise however it has gotten worse with the more miles i drive. Now that im out of warranty i guess im stuck listening to it until i trade it in.

  7. So my truck still makes the noise. Fuel feed pipe didn’t work. It sounds like it’s literally right below my feet. Most annoying sound in the world. Bummer too because it’s such a nice looking truck.
  8. The tick is mostly gone. And by that I mean that I can hear it very faintly once in a while but it seems that it goes to V8 mode or upshifts right away. If I didn’t know about the tick I wouldn’t know it was there. Much improved!
  9. It’s located between the chassis fuel line and the high pressure fuel pump. It seems to have done the trick on mine. I’ll keep you posted as I drive it throughout the next week. The TSB was PIP5395D.
  10. They changed my fuel feed pipe and that seems to have fixed the issue!
  11. Ok so this is weird...I’ve ran my heat in my truck for the past 6 months because i live in Minnesota and it’s be winter that never ends. Well today it was nice enough to have the climate control system off and the truck didn’t make the noise!?! Could it be that it has something to do with running the interior fan???
  12. Rick,


    Do you still not have the footwell tick? Curious if what you had done is the fix for the issue.

      The tick is gone since the drivers side exhaust manifold was replaced.

  13. I just stumbled across a response that seems like there could be some logic to... After numerous rides to the dealer and talking to several techs, one answer finally made sense. The valve package of the transmission is located on the drivers side. These 6-speeds are super smart, and when the truck is under lightacceleration, in a high gear like 6th, basically lugging, the transmission starts to preload the gears for optimal gearsection. You can hear right before the shift the clicking of the solenoid valves in the transmission. It is completely normal. I've always thought that there seemed to be a correlation between the ticking and the tranny. It seems like it’s in the drivetrain and not so much the motor because it doesn’t do it when you rev the engine and it directly correlates with the RPMs.
