Chasing the stumble at idle I rebuilt the throttle body with a $15 rebuild kit off eBay and had no change. I pulled the IAC to clean it, got too aggressive and broke the plunger so had to spend $40 to replace that, no change. Did the paper on the exhaust pipe trick and the paper got sucked in, meaning an exhaust valve was not sealing. Fearing my $1200 Craigslist truck was not such a bargain and needed a rebuilt motor, I shopped Craigslist for a new set of heads. Decided to pull a valvecover and found that when the previous owner had his mechanic replace the intake gasket and relash the valves, he tightened the #1 exhaust valve too tight and I could not spin the pushrod with my fingers. Relashed that valve, and the idle stumble is solved, and it runs extremely smooth idling at 600rpm.

With the engine running smooth, I turned to Craigslist for new wheels with no peeling and found 4 wheels from a 99 Tahoe in like new condition wrapped in tires with 40% tread for $50. I installed them and sold 3 of my peeling wheels for $210 and kept the 4th as a spare. Old wheel on top, new on bottom.
