Check the spark plug wires. It might be one of the spark plug wire boot is loose and causing an arc between the engine and spark plug wire. Check this at night, if you see an electrical arc between the engine and spark plug boot, then you found the culprit. You can change the spark plug wires(recommended) or just put electrical tape inside the boot. Let me know if that was the cause. Thanks and good luck.

I had the same thing on my 02 rover and it was the coil pack. I replaced both coils and it worked
