Last fall I took my car to our mountain house to store it in the garage over the winter. About half way there (still around sea level) it started to mis. Unfortunately it was late, I was at the foot of the mountains and therefore had no service, I was forced to drive it to the house. As long as I kept it at around 4,000 rpm it didn't miss but was low on power. I think it's running lean, it used very little fuel on the way up. So now I have a car stuck on the mountain with no shops for hundreds of miles. I'd like to take a stab at fixing it and driving it home. At first I thought it was the afm but the un-plunging afm test turned up nothing (I also replaced it 3 years ago). The symptoms do seem similar to what I experianced last time it failed. Could it be O2 sensors? What do you guys think?
Cheers it's almost Boxster season!
