    No check engine light?
    If the light's on, the light indicates that the computer has detected a malfunction in the engine/transmission control system and has diagnostic codes and data stored which would be essential in diagnosing the problem.
    A technician with a scanner can access the diagnostic codes and data and then be able to give you a diagnosis.
    If no light, check out the ignition system. I think that misfire under load is usually poor ignition.
