How about an organizer tray for the inside of the center console? I know a guy that has one. Pretty sure he'd trade it to you for your decommissioned cup holder insert if the doors aren't broken.

I bought one of those too. Thanks though!

Do your DRLs seem to go out often? Just curious as mine always seemed to. I just stopped putting them in. I always see our gen Tahoe's and Avalanches with one or both DRLs out.

The fix for this is to install a 4114 bulb that can handle the voltage spikes. Manual calls for 3157 but GM issued a bulletin to install 4114.

pulled the center dash speaker out again and re-did my foam padding support fix, the foam padding was just loose inside and the speaker was bouncing up and down again so I folded the foam padding wrapped it in tape and then double sided taped it to the bottom of the speaker now it is nice snug again, now the speaker supports the dash instead of the dash supporting the speaker causing it crack more. Also added a positive wire directly from the alternator to the 2nd battery (like the early nbs's are setup), mobile 1 oil change, tire rotation, and got a free car wash.

I wonder if new plugs and wires might help?, the engine came with new plugs and it has 34k on it, the wires I think are the original @118k, I scanned it the other day with the tech2 and I don't have any misfires, the fuel pressure says 40-44 while running, 70 when I shut it off and have the key on
