Going to get a new multimeter to confirm but pretty sure my coil is dead or barely working.
Started fine yesterday then today it started for a few seconds with a very low weak idle then died and ever since it’ll crank and backfire once in awhile, exhaust has smoke coming out, fuel pressure and fuel quality is good. Unplugged my programmer and no change. Unplugged the wires from the coil and the backfiring stopped. I also cleaned the grounds, checked the air filter etc..
I sprayed some ether to it and same thing it’ll backfire and smoke but won’t fire the cylinders. The spark plugs are ngk iridiums with maybe 250 miles.

Last weekend I went to disney, ok and had zero problems. Anyone been thru this or something similar? Doing a search I didn’t really pull up much about bad coils.
