Ok last night I was driving from McDonalds to my friends place and wile I was driving there I came to a stop at the light and my car died wile at idle. I have notest my revs have bin jumping up and down too when I throw in the clutch usually when I was just kind of giving it. It go's from about 1500 to oh around 100/200 revs when its jumping then it come to about normal idle at 800 and stays, could it be a dirty fuel system ? or is it some thing else ? any one had this problem too ?
