Hyundai Repair: 1996 Hyundai Excel misfiring at low speed..., hyundai excel, leak test

Question
My hyundai went into a shop to get diagnoised but there computer couldn't find a problem as the misfire/cutting out did not occur while it was connecte dto the computer. So they got a person in whose computer was sure to find any defect over the last month of running... no joy in this department. The problem would happen when the car was cold and hot but only when running at a low speed 5-25km. I you can please help me.

Answer
Hello Sam,
It is really hard for me to tell you the problem with so little information. All I can reccommend is to make sure your spark plugs , wires and ignition coil are ok. Also it is a good idea to have a compression test and Cylinder leak test performed.
