thanks overcharged I may take you up on that
So on the way home tonight I had the injector light on the dash (engine warning).
Anyway ive done a few things to no avail:
Pulled off and cleaned all injector plugs
Removed plugs and cleaned
Pulled off and cleaned coil plugs
Pulled off and cleaned relay's by battery
White plug under dash pulled and cleaned
Now all of this did bugger all and as soon as I restarted the idle was lumpy at around 600-700 (the bar on the Tacho) if throttle revved slightly it will drop lower and then rise and fall a few times between say 400 and 1000 till it settles to a lumpy idle at 700ish.
Drove off and it seemed to rev cleanly and work well. Got to the end of my road (5km or so) slowed to turn around and idle was still lumpy.
Accelerated away and it was missing (or thats what it felt like) every now and then it will clear, but soon comes back.
The engine warning light has gone though...
Maybe its a coil pack, I have no idea how to check? Spares aren't exactly easy to come by in NZ for these!
