right then people, got a problem with my mates Esort tubby. Start the car in the morning fires up mint and runs sweet. But has developed a problem! Once she is warm she has started to cut out and refuse to start. will be driving along come to some lights then it will just cut out. Some times it will have a massive misfire and cut out. Changed coil, dizzy and rotorarm but still does it

anyone got any ideas??

 

more than likely be a air leak. check all vaccum hoses and boost pipes for splits etc.
