I bought a 91 Stealth RT TT back in August and I love the car. It only has 49000 miles on it. Anyway, since the weather has started getting colder it has developed a problem. When the outside temp is below about 50 deg. the car has a kind of stumbling idle and hesitates bad when accelerating. The faster I try to accelerate the worse the problem seems to be. It's most noticeable in 1st and 2nd gear, but also in 3rd. After the car warms up the problem mostly goes away, but still doesn't feel exactly right. Anybody else had this problem or maybe know what's causing it? BTW, the car is stock.....for now!
