Just bought a smoke machine.
Found it! Previous owner had the catalytic converter replaced about a year before he sold the truck, and apparently the exhaust shop didn't bother to tighten the clamps on the silicone AIR hoses....
Complete PITA to get to, and most of the work was done "blind" and one-handed, from underneath, but I got it.....1/6th of a turn at a time.
Truck runs pretty decent now, and despite the crappy mileage I get with the 460, I'm going to use it as my "commuter" the next few days (34 miles each way) to really check 'er out.
