Stalling - P1638, P1639 Throttle Valve Position Control
Over about the last month, my car will randomly stall when completely warm usually when starting from idle. It has only happened about 3 times.
Then today, it did the same thing, except this time, it didnt quit, but idled up and down between 400-500 RPM. Luckely I had my code reader handy and read: P1638, P1639 - Throttle Valve Position Control -Throttle Stuck Permanently, Temporarily. Now these codes were pending and erased as soon as I started the car the second time.
Any suggestions as far as what to do? I have a 1000+ mile trip scheduled at the end of this week and am looking for some ideas.
