Hi

My Mazda 323 keeps switching off while I drive at any speed totally randomly.I had the battery and alternator tested and they Ok.I replaced the coil and plug wires aswell as spark plugs.Also sometimes when I drive if I stop accelerating the car will switch off.What could be the problem?

No to the plugs, but check fuel pump pressure. It could be weak.
