Check the TPS and coolant temp sensor at the coolant neck, those could cause poor fueling and bad acceleration. If you can get it scanned that would be better because then you can see if the TPS shows a faulty signal when you press the throttle, Or you can see the temp sensor to see if its in the negative 40 range...(typically where it goes when it goes bad)
