Finally! Lights!

Finally got around to upgrading the lights on my '07 Denali. I've been running the usual Amazon LED stuff for a while, and while they're always bright enough, the build quality and beam pattern have never been great. Most of them also advertise "high beams," but they're barely any different from the low beams. I decided to give Lasfit a try, and honestly, the high beams blew me away. They're actually a true high beam with a ton of usable light down the road, and the beam stays consistent instead of scattering everywhere. The bulbs also feel much higher quality than the other plug and play LEDs I've used. That's probably been the biggest surprise for me finally finding an aftermarket LED that has genuinely impressive high beams.

Is this lifter tick?

2010 GMC1500 5.3l vortec. Trying to figure out this noise. It never really goes away. I kind of gets quieter when I've driven a little but but I still notice it. Definitely worse in Idle. I run a electronic AFM disabller but I just got the truck and it has 180k km on it.

[USA] Anyone in the Houston area recognize this black Yukon with custom rims and a trash bag covering the back left window? My friend's car got broken into and got their tools stolen.

Misfire

2014 sierra 5.3. Afm is disabled, no ticks or knocks.

While driving yesterday going up an incline I felt it kind of bogging down so I gave it a little more pedal, didnt floor it just gave it some extra. It picked up, but then I got a ce and stabilitrak light simultaneously, ce is constantly flashing and stabilitrak is steady on.

Scanned it when I got to where I was going, p0306, cylinder 6 misfire. Immediately replaced coil without any further diag. Didn't fix it. Today, swapped plug, wire and coil with cylinder 4 and misfire is still in 6. Whats my next step? Compression check?
