Hey Folks!
I been lurking for a couple months. I bought a 94 Ranger 2WD manual 2.3 just recently. It has ONLY 94k miles!
It didn't run great when I bought it, but I've gotten it seemingly smoothed out quite a bit with some basic maintenance. (plugs + wires, trans oil, diff oil, O2 sensor, fixed a vacuum leak on the exhaust, water pump, thermostat, timing belt, fan clutch...... ummmmm think that's it...
It runs okay now, seems a little weak, and maybe mild hesitation at mid to higher RPMs.
I've been banging my head against the wall trying to troubleshoot a CEL code 222. (IDM "high" or open or coil pack bad) I've discovered that IDM is ignition diagnostic monitor... and I figured out which wire it is on the ICM... But I don't know what "high or open" could mean....
I've done quite a bit of diagnostics
Tested coil primary and secondary impedance.
Checked ICM ground.
Both coils and ICM are getting 12v.
I've got continuity between each of the ignition terminals on the coils (2 outer terminals on each coil) and the ICM.
I have swapped the coils to see if I would get a different code (I believe code 218 should have come up if a "bad coil" was moved to the other side) Still code 222. It also ran the same after swapping coils.
SO then I attempted to start it with only the exhaust side coil - it started, and ran like crap heheh.
I decided to check spark by carefully pulling the plug wires off the coils one at a time while the engine was running (safe?.... maybe...)
It appears that on the exhaust side, coils 1 and 4 are not sparking. AND on the intake side, coils 2 and 3 are not....
Am I really running down half a coil on each side? Or is there a condition where half the plugs on each coil arent supposed to spark?
I've been going thru this diagnostic series... https://easyautodiagnostics.com/ford/2.3L/icm-and-crank-sensor-tests-1
And haven't gotten to the Crank Sensor test yet....
Let me know if yall have any advice!
