Hi bigierhymer, A "Fuel Trim Malfunction" is normally referencing codes P0170 or P0173. This can be related to a variety of issues ranging from vacuum leak to MAF sensor failure to manifold gasket leak. It would be best if you took into your trusted mechanic or dealership to have this addressed. Good luck!
