My 1998 audi a4 1.8T has recently been sputtering when i accelerate..it almost sounds like a go cart..there isn't and engine noise so i dont believe there is any valve or piston trouble..i think it may be spark plugs or O2 censors or something to do with the fuel injectors, pump, or anything related to the fuel system..if you could think of anything that would cause these problems please let me know..Thank you
