I had some injector problems, I cleaned the injectors which made the car run rough and stalled inless revving the engine. I tried the iyalian service which produced a loud ticking noise which will not go.

I have replaced and recoded the injectors/ecu, cleaned the TDC sensor and the fuel pressure sensor but the tickin perssists.

The car now runs fine, all errors have been cleared and don't come back. When I pull each of the injector plugs off in turn they all sound alike but ticking continues.

I have not moved the car from the drive in case the noise leads to something catastophic.

Any help please.
