Well, been driving it some more. The people who had it before me took some black tape and taped over the 'Check Engine' light in the message center. They even went so far as to use clear Scotch tape across the entire face to hide the fact it was there. Yup, check engine light is on, and fuel mileage display says I am getting 16mpg (that is averaging the city/hgwy driving I do in the normal work week, with more of it being city). I assume it is probably either EGR or an O2 sensor failed (will find out once I get it back to Florida and hook to SCT scanner to it.
Also noted that the car is still burning the trans fluid. The 3rd cat was SOAKED from the old trans rear seal failing, and I imagined it was from that. But (to me anyway) it has been too long and driven too far for it to be that. I will take it back in next week for them to look it over before it hits the road for Florida.
Dash lights are acting odd now. They will not come on when I turn the switch over to activate the headlights. It takes a special VoDoo to get them to come on. I have to stick the key in the ignition, roll it to the Access/run position, turn the lights all the way on, then start the car for them to stay illuminated. All other light functions work properly. Again, I will dig into that when I get back to Florida. Are the Puddle Lamps supposed to come on when you open the door? If so, I need to look into that as well, as no puddle lamps happen.
Post Script note: no rear window defrost either, the switch is there, but NO WIRING going to it! The dealer who back-halfed it must have not run the wiring, figuring the car was staying in Kentucky and wouldn't need it!
