hesitation
At fast execeleration engine hesitates badly; this condition can also be duplicated with engine running at fast idle (4000rpm) in park. This problem was notice shortly after a battery cable became loose and sparked upon starting. Compresser seems to be working fine even durring hesitation. Engine idles smoothly and runs fine in normal driving conditions but if I have to get out of someones way, that can be trouble. Engine light will come on if kept at the trouble spot.
