So, I was head down the highway at 40MPH, she shudders and engine cuts off. This was in LA on Sunday. Towed it back home to SD last night and tarted doing my research.

117K miles, timing belt at 97K, battery is good, fuel pump is good, relays are good, fuses are good. Checked cam pos sensors and both are good and their harnesses are both reading the appropriate values, no shorts there either. I'm at a loss of what to check besides the Camshaft Adjustment Bank 1: Malfunction. I don't know what or where that is and google hasn't helped much. Here's what I've got going on. Cheers.

Looks like the chain broke, so it's pretty much certain that you've got bent valves. The pistons are usually OK when the timing goes on these V6's, but I have seen a valve break off and bust a hole through the top of the piston once. If you're comfortable wrenching, the removal and installation of a head is not extremely difficult on these - it's just fairly involved and time consuming.
