Yikes!

My 92 Sentra E 1.6 started missing, badly. Local auto shop
said....needs Injector.

My mechanic said, "Phoooey", let's replace all the electronics
pertaining to ignition.. plugs, condenser, rotor, wires,etc,( except
for distributor too expensive for trial and error diagnosing)

He did, and it still banging on 3 bangers instead of four. Swapped
plug cables...still missing on the same plug!

Mechanic conceded it needed an injector. I disagree, There's no or
little spark from plug #3. What does the injector have to do with
it????

I say it's the distributor. Any thoughts??

Thanks
Mike
