Engine shakes at idle and when you accelerate it shakes if he is off the accelerator it seems to clear out a little bit a friend of mine put it on his handheld computer and it said that the fuel pedal positioning sensor had a weak signal and was misfiring on all six cylinders

GOOD MORNING MY NAME IS ROY AND I WILL ASSIST

THE FIRST THING I WOULD DO IS CHECK THE PLUGS, WHILE THEY ARE OUT, DO A COMPRESSION TEST TO VERIFY NO INTERNAL DAMAGE TO THE MOTOR.
CHECK ALSO FOR SPARK TO ALL CYLINDERS. COMMON FOR COIL FAILURES AND MODULE FAILURES AS WELL.
I WOULD START THEE AND REPORT BACK WITH YOUR RESULTS

ROY
