Believe it or not it is actually a noticeable difference with the M3 in cold and hot feels as if its more labored..descriptions are subjective so saying it runs like crap may seem extreme to us but maybe not to the OP

My suggestion throw a bottle of techron in the tank and see what happens..again just taking a shot in the dark here.
