2012 fiat 500 lounge 1.2 petrol manual.
Hello
Issue I'm having is:
car seems to start and run fine and engine ticks over fine until I switch headlights on then the revs start to fluctuate up & down to the point where it almost feels like car is going to cut out also headlights start to dim then return to full brightness.
If I hold revs just above 1000rpms then the issue gets better.
I've changed coilpack plugs & leads & tried to inspect wiring but not found anything out of place.
I did get some engine codes referring to miss fires which is why I did coilpack leads plugs but not sure if the missfire codes appear as part of the above issue ie once lights are turned on and car idle goes mad
any ideas or advice is appreciated thanks
