Over the past few days my 2002 has been feeling like its been miss firing
This morning when waiting atvacset of traffic lights an engine yellow light started flashing then stayed on and the car sounds awful and running on 3 cylinders.
I thought maybe plugs or leads so popped out in my car to buy some when I came back to fit the light has gone out and running fine ?
Is their a program I can download and use to diagnos what tht problem was ?
I've got a lead just don't know wha software to buy ?
Any help appreciated
