- Immediately after a full run when the car has been completely warmed up, I would immediately pull all 6 spark plugs and see if you've got any differences between them which may indicate an igniition fault or injector fault on one or more cylinders
- as you've got a smell of gas plus difficulty starting and misfiring even when warm, I would try starting the car, getting it slightly warm so it won't stall and then disconnecting the coolant temperature sensor and see what happens. The sensor enables enrichment to aid starting and warm-up. If it's failing, it could be causing any of the symptoms that you describe.
Good luck

Thank you Paul for the suggestion i will definitely try these steps
To add to that excellent suggestion from Paul (ptjs) you can Bridge the Wires on the Coolant Temperature Socket, to fool the ECU into thinking that the Injectors are over fuelling and cutting down on the supply, in what is known as 'The Paper Clip Trick'
'The Paper Clip Trick' to Test to see if the Coolant Temperature Sensor is working ok
