misfire ?

I suggest testing ignition wires spark plug wires. Are you able to use and understand a A.C. volt meter, if yes ohm resist 1 wire at a time engine Not running verry important remove wire both ends check ohms resistance compare all a bad wire will have much higher number reading amount. good luck that is a start if test ok.

Sounds like (yet another) coil pack fault - especially if the engine management light is on.
