hi all my saph had a miss on boost when i bought it , did all the usual, plugs,gaps etc etc, and fitted a group a coil as considering the price i thought it was a good idea. all was fine car pulled like a train and sorted the local scoob owners out lol, however lately the miss is back and ive noticed while cruising along that the rev counter is jumping around all over the place , could this be the coil , its only been on the car 6 weeks

forgot to mention that the original miss was down to every plug having a different gap, set new plugs to 0.7 , and original fault wasnt effecting the rev counter in normal driving conditions, any help

cheers

The tacho can affect the ignition, just temporarily disconnect tacho and see if that sorts it.
