Hi there.
My 87 244DL is having trouble idling smoothly. I checked the injector voltage by backprobing them, and was only seeing 0.5-2.0 volts across the terminals. Unplugging them during idle seems to have no effect either.
I've even tried backprobing PIN 13 on the ECU, and I have similar readings. This is the 2nd ECU I've tried. I'm stumped! Any ideas?
**Forgot to mention, the positive pins at the injectors have 12 volts.
