I have a problem with my car and I don't even know where to start. The problem is that when the ambient temperature is low(winter temperatures) or the weather is humid??, the car hesitates when I accelerate and is jerky when I go on and off the trottle at low rpm. When i drive it's like it has half the horsepower when I press the gas, and then after a few seconds it suddenly decides to accelerate like normal. When this happens, the idle is bad too, it goes between about 1000 to 800 rpm, but when it goes to 800 it starts to shake a little. When the problem happenes, I also think it may misfire a few times. After some time, when the car is at warm and at optimal temperature it starts to drive and idle like normal. Does anybody have any idea what the problem could be? Its a 1996 Celica st200, 7afe engine.
