Hi. I am new to this site. I hope you'll can help. I have an occasional problem with my car, especially on Mondays when I don't run the car all weekend. On monday mornings, I take off to work. Like around a mile or so, I step on the accelerator and the car starts to jerk, stutter, like it wants to die and I can't give it gas. It does this for a few seconds then goes away. I then give it gas to go faster then it starts again like hesitating real bad then it goes away for a few seconds. Like around 10 miles doing this, it slowly goes away. It doesn't do it in the evening when I go home. Could it be moisture or a gas problem? or electrical? I have replaced the crank shaft sensor twice cause it would just completely turn off on me. Could it be my spark plugs? It has been a year since I changed them and since then I have had this problem. I just recently replaced the wires and it still does this. What do you suggest? It used to do it more often when I let the gas gauge go low so since then I have had at least a quarter of a tank or more but I today I had half a tank and it did it this morning on a Thursday... What do I do?
