when drivin the car starts to feel like it is miss firing, then then speed gauge drops to zero, the the mileage stops clocking up and the fuel gauge sometimes fluctuates. Occassionally the digital readouts go to a series of dashes and the rev counter also drops off. The car will settle down until i need to change gear and accelerate. Turning the ignition off then on will reset everthing but only for a matter of minutes then it all starts again. The car never actually stops. The EML never comes on and the cumputer plug in showed no faults. Have anyone else had similar issues, any ideas how to fix.

sounds electrical. Maybe ignition switch or relay? Bad ground also a possibility

Thanks I got it sorted. Turned out to be the coil pack, the EML eventually stayed on and showed a coil fault. Changed the coil pack and all faults cleared. This explains the miss firing but it must have also been shorting some how to cause the instrument issues.
