Safe to change stock coil? 200 1979

Paul:

If the coil measured out of spec, it may very well be bad. The question is, where was stuff measured? If you're not able to measure directly on the coil, your readings may have been influenced by poor wiring.

JenaBob:

The same coil may not be critical. My 84 and 85 have different coils (but same ICU part numbers.. hmm). When I swapped the ICU+coil from the 84 into the 85, I got some less than desireable results. Same Bosch part number isn't necesarily critical, but it's a very good idea.

I agree that the fuel system is probably a bigger suspect than the ignition one. Except.. if your car has a ballast resistor.. that could, in theory, be causing some problems.

Does your car behave better with a full tank of gas?

For ignition components, go for:

Bosch cap+rotor
Bougicord wires (or anything other than Bosch wires)
NGK plugs (BPR6ES or BPR7ES seem to work well for me)
