What was your resolution to your throttle body/idle position sensor issue? Did you have your car fixed with a dealership afterall?? I have an '03 Solara and same issues as well. I'm looking at an alternator, throttle body unit, and/or an idle position sensor..have a 2002 solara (same engine as a camry). 85K miles, car dies on the road, toy dealer says $1200 for a new throttle body. SOL and pissed, but probably not as bad as if kept my Saturn for that many miles.
