Hello Ladies and Gents. Merry Christmas.

My engine management light flashed and stayed on this morning.
I was accelerating through 3rd to 4th gear (up to 5,000 rpm) and the same with 4th to 5th.

Took the car to a mate who plugged in his OBD reader and it displayed the car had misfires in cylinders 1, 2 and 3. He reset the alarm and off I went.

Is there anything I should get checked out just in case it all goes pete tong
