Dodgy rev counter and missfiring?
On my 2wd cosworth im getting a problem with missfires and erractic rev counter. My rev counter doesnt work at all for about the first five mins and the car runs fine. Then once the rev counter starts working its jumping all over the place and then the missfires start when driving around normally. Then suddenly the rev counter works fine and there are no missfires for a few mins and then goes erratic again and missfires start etc etc.
Does this sound like the phase sensor or phase sensor wiring being intermitant?
It has got a coilpack conversion aswell, could it be the coilpack going down?
