Thanks guys for all the help!
I have only had the car about six weeks and I can't remember that the power light blinks at all when starting. It does comes on when I stab the right pedal though. What does 16 blinks indicate? What does something other than 16 blinks mean?
All the tires match and have less than 5k miles on them.
If the TPS is not less that .5 volts is there an adjustment or does it need replacing?
I know little about the car and apparently the tranny shop doesn't either. They knew it was a 4EAT without looking it up so I gave them credit - maybe un-due.
I'll probably pick it up tonight and try the figure eights to see if that helps remove the clunking.
