Rough runner
I have a '94 Ford Ranger pickup. It has only 62000 miles on as I ride
my bike a lot. It has been a good runner until recently when one day I
started it and the engine ran as rough as if one cylinder was missing.
Out on the street it smoothies out a little but lacks power. Since
it’s drivable I’m trying to troubleshoot it myself. It has the 2.3 L 4
cyl. Engine with distributorless ignition. I’m thinking that the
probability is that the problem is not the ignition because of the
relatively low mileage, the two ignition modules and two plugs per
cylinder.
Does this make sense? My guess is a clogged fuel injector. I put in a
bottle of Gumout fuel injector cleaner and have driven it about 40
miles with no results.
How long does it usually take injector cleaner to work?
is it possible to use a scanner on it? i don't see anything about that
in Chilton's.
Any other ideas?

First thing I'd check would be the spark plug wires. With the engine
running, pull the wires off each plug, one at a time, and see if anything
changes. (You may want to wear leather gloves, or use a rag for this.)
No change = dead cylinder; swap the plug wire with one of the others and
see if the problem follows the wire, and go from there.
