i've been having issues (misfire, rough running - totally intermittent) with my 1984 turbo wagon and i think i've tracked down the issue...
when i pulled the spark plugs to inspect them #2 and #4 showed normal wear, but #1 seemed to have some fuel on it, and #3 seemed to be mostly saturated in gas.
i did the poor man's stethoscope trick (my ear up to a long-handled screwdriver) against each of the injectors and all seemed to be firing as normal with a consistent pulse, same volume.
leaky injectors maybe?
is there a way to test the injectors with a multimeter, maybe for resistance?
