thx Ps2cho; Bought the wagon about 3 years ago...owner said O2 was "newer" but seeing what I saw after pulling motor/tranny I doubt everything he told me. I'll be starting there...hoping the cat is OK. What is a good not too lean or rich figure for %CO2?

Suggestion on aftermarket lock cylinder shop? It would really be a mess if key gets stuck again. Car is parked underground till I make a laundry list of what to fix before ging in for retest.
