Car was not running properly

Volker just read the Petronix info and it says the coil must have a minimum of 3.0ohms for a six cylinder..Or buy there 40.000 volt version with internal resistance.I will need to see what the BMW one is rated at.

Volker thank you Nigel.

Hi Volker.Im pleased to say after many weeks of trying to get the car running properly I've found the problem.It was a faulty throttle switch.also I was give the incorrect information as to how to set it.I have replaced the switch and have fitted a new coil.My Petronix is the so called Igniter one which is a black module and with this there should be a 3 ohmn coil so I bought there version.and I'm pleased to say the old car is back to her normal self ! Going like a rocket.
