I have had the check engine message come on couple of times when the car has been started when hot. All started after I changed plugs and HT leads.
I have a hand held Autel 509 and PC based ELM327 setup. The Autel picks up live data but does not read any error codes and the PC ELM does not connect. Anyone recommend a hand held system that will work correctly?

Car is a CV8 big boot type.

Thanks

Thanks for that information.

Any one tried the D900?
