[agfours]

I have an '86 Coupe, all stock. I'm getting an engine cut out at full throttle (similar to a rev-limiter) when at 5k+ RPM's.

I recently replaced plugs, new Clewett wires, Bosch rotor and cap. When I examined the coil at the time, ohms were slightly out of spec, plus it had a chip out of the ceramic port on the top of the coil. I suspect this could be the issue of the cut out, and since it is out of spec, want to replace. However, I'm seeing bad reviews of Bosch coils.

Any recommendations on alternative coils? I'm seeing some using MSD high vibration used, but mostly on CDI/earlier cars. Would this work on a stock '86 3.2?

Other ideas? I've seen some recommend cyl temp sensor replacement for a similar issue, as well as resonant vibration in the dizzy. Dizzy is certainly worn with ~108k on the clock. Looking to examine from easiest/cheapest to more expensive if this turns into a parts replacement quest.

Of note, and as a related question, I replaced the old Bosch WR7DTC (three prong) plugs with NGK BPR6ES's, and seems to have a little less power. Recommendations?

TIA!
