2007 Montego "Wrench Light"
What can cause this light to come on? I have 80,000 miles on it. It only seems to light up and cause a bucking hesitation when it rains. It doesn't do it when it is dry out. After googleing it, it sounds like a Electronic Throttle Body issue. If it was this, wouldn't it happen all the time not just when it rains. Please suggest what could be going wrong.
