Yesterday I removed the cap, was curious how it looked...Also wanted to test the ignition module which I did today... It failed completely... Upon further deeper inspection I was taking note of how original the actual distributer looked... I also was checking wiring which appeared to run from ignition switch to ignition control module then out to the rest of the electrical it goes... So anyway, got a new distributer that's getting put in Monday due to weather in my area... Crispy wire ? Yup, I keep that in the back of my mind while I looked it all over...Datalog that captures the engine bogging might lead to some results.
There could be a crispy wire somewhere that stops working when hot. All electrical work is resolved the same way and to quote a guy from another place, its eeeezzzyyy you just have to physically check all the wires.
One of your new parts may be working incorrectly, or installed incorrectly, or physically fits but is wrong for the vehicle. All cheap junk parts are suspect.
