hey man that's what we do here....we help each other keep these cars running right!
Look, this will get worse over time. It may get to the point that the miss will start almost upon start up. It's the epoxy on the coil windings that is the issue. The more exposure after the alcohol gets to eat thru some of it, the faster that hole becomes bigger.
A scan in closed loop at idle will yield the BLM's & INT's, and O2 info...they will tip you to the ECM trying to add fuel to make up for the injector(s) not squirting fuel. Also, the p[lugs will be a tell tale as the holes with the bad injectors will look too clean to have had combustion. Also, if the miss is really bad at idle, go sniff the exhaust. If it make your eyes water and smells pungent then that's you smelling a lean condition.
Also, when you do an ohm test on the injectors you can go thru the ECM harness. A word of caution here. The ECM plugs have very small female terminals, so don't stick a normal test lead from a DVOM in them, use some phone wire. Reason is that you can deform the terminals and end up with an intermittent contact! Be very careful if you ohm the injectors that way.
