Engine Misfire After Plug Gap Alteration

Hi

I thought my Mk1 was running a little (low mot and soot on the tailpipe). I checked the plug gap which were well 2mm. Manual suggests for a 1.6 Zetec they should be 1.6mm. However it now misses between 1000 and 2000 rpm. Fine above that rev range.

What gap do you recommend for most beautiful efficient burn?

Thanks.

Craig.

    1.6mm sounds a bit too much, I'm sure the revised gap is 1.0mm from 1.3mm

    The coil pack has probably had it.

    Thanks guys. Managed to locate a thread on coil packs also suggesting 1.0mm revision. I'll try that first. Failing that I'll try a new coil lack. Any harm in motor factor coil pack of stick with Ford gen parts?
