Re: Torque Convertor
So you're running a dual fuel setup? Well, if the problem happens regardless of which fuel you selected, I would suspect the ignition system (leads, plugs and coil, in that order). If it only happens on petrol more than likely it will be blocked injectors or filter (petrol crystalizes inside the injectors if you never use them) and if it happens only on gas check for air and vacuum leaks or dirt inside one of the jets of the converter. Is there an engine light on? How many miles has this car done?
