Hey, I just got to thinking (something new for me), That won't work, aren't
those injector pulses timed for a particular cylinder????

if you swapped the injectors did you swap the injector leads from 3-4 or
just move the actual injector. if you put the 3 injector plug on cyl 4 and
you still had a miss id say do a compresion test. try feeding the injector
power from a another injector.  
 
------------------------
Looking for some help. I have a 92 Eagle Summit (Mitsubishi Mirage) with the
1.5L engine.

The engine misses on the #4 cylinder. I've done everything I can think of

except change out the ECM (fairly costly on this car). I have checked
compression, changed out the

integrated distributor, changed plugs and installed new plug wires. I have
also swapped #4 injector

with the one next to it and the problem remains on #4. I put in a NOID light
on #4 injector harness

and it does light off and on. Now I'm lost. I have also removed the ECM and
replace to two

electrolytic caps that others say causes problems on these cars, still
misses. The ECM shows no error 

codes. I should probably part this car out, but I'm a little stubborn and
don't want to let this thing beat me.

Any ideas?
