Well, I took my 'teg to an exhaust place and the cat was as clean as can be. So I then went to a local mechanic and while he fiddled with the spark plug wires, the car died and it wouldn't restart. I didn't plan on leaving it there overnight, but I didn't exactly have a choice . This morning he called and it was fixed. The culprit, a dead ignition coil.

I don't know if these things take their time in dying or what, but this car seems to have a lot more umf than it did last week prior to the obvious problems. But alas, my 'teg is alive and well again and I am happy.
