After misfiring and the rev counter now fluctuating, I have whittled the problem down to one of two things (hopefully ) It is either my coil or my coil pick-up. Its down to trial and error now and I have managed to order a new coil, but need to know the part no. of the pick-up. Please help, if you can't quote it could you give me a link to somewhere that can help.Oh yes and the distributor is the stock one that came with my ZZ4.

Thanks from 'Across the pond'

Is the distributor the coil in cap style or not? That should help narrow it down between the only 2 different ones I know of that GM used.

 

madmax Hi! Yeah it is the one in the cap with a yellow, red and black wires.

Thanks
