So I have a 2005 dodge neon I purchased a few months back replaced the spark plugs and spark plug wires the week after I purchased it, well just recently when I take off from a stoplight it sputters a little then goes, any suggestions? I have run 2 cans of BG Gas treatment through it in the last 2 months I was thinking coil pack or possibly bad fuel? Fuel filter clogged? I installed a new air filter two months ago, 128,000 miles
