I have a '97 Cinquecento S and I seem to have a problem with the engine. Lately when I've been driving the car, it seems to be jerking as if one of the cylinders isn't firing, also a red 'injector' light appears on the dashboard. I've changed the plugs today for starters but it still seem to be doing the same thing. It's not happening all the time, just sometimes.
Any suggestions are welcome.
