Hi there, I picked my V12 E-type up from the garage last week but for some reason it started to back fire and smoke but only after I had but fuel in at the local petrol station. I have started the car this morning and the car started and seem to run without back firing. Could this be due to over fueling, my coil or something else? The car has been fit with a immobilizer which has been on the car for a good few years but I don't think it is due to that but I could be wrong. Any help welcome as I would like to have my car ready for show season.
