Another noise when cold starting
I have a 59 reg "S" with 41K miles. When I start it first thing i.e. cold, it seems not to be firing on all cylinders. Some times there is a "pop" from the exhaust. When I first started having this problem, I could "blip" the throttle and it would clear but now I have to stop and re-start it - sometimes twice. Once running smoothly it runs well and it always starts well when warm. When it is misfiring there is a smell of petrol at the back, i.e. it seems to be "over-fuelling."
Nothing comes up on a cheapo OBD2.
Any ideas to help diagnose the problem?
