As above any tryed and tested diesel bug additives you can advise. Not injector cleaners.
Thanks.
How do you think your truck has got contaminated Lexie? I mean, has it been left or had anything out of the ordinary? Biodiesel perhaps? Just curious as I've had a vibration in my engine for a while and wonder if some of this might help.
There is a filter inside the injector pump and also filters in each injector. Designed as it should be to isolate the separate components in case contamination gets in not just through the tank filler but also by work done on the car, EG changing the main paper filter could cause contaminants to get in to the pump.
