Have a 1999 Sunfire with a auto trans and 4 cil engine. Some times when comming to stop or to make a trun. Engine acts like it wants to qiut. Also som times thier is a slight hesitation when starting off. Engine light is not comming on. My 1st thought is the fuel filter. So I,m going to put a fuel filter on and also poor some of that fuel cleaner in tank. The car all ready has a new air filter. What could be some other possibilies. Thanks, John.
