first off, when started, if you try to take off it stalls and doesn't throttle up, falls on it's face if you know what I mean. once warm up a little then it will run, but you stomp on it and it sputters some while accelerating... then it can run fine for a while, and all of a sudden you will be at a stop light and it will barely pull away till you play with the gas pedal some to get the rpm's up a little.. anyone that can help me with this would greatly be appreciated.
