Why doncha RESOLDER all the Main Relay cracked solder joints,and ELIMINATE
the main relay as a trouble source?
Then you can check other things if the trouble still persists.

When you don't have $40 at your disposal, sometimes you have to make-do.

Planning on doing just that. I was just wondering if the sputtering
could be caused by timing AND/OR the main relay?

The Main Relay is not associated with "sputtering". But then I've never
encountered anyone who has driven around with it unbolted, either.
What you may want to do is to bolt it back in place once the motor is
running, and see if the sputtering is gone.

One thing that occurred to me, that I didn't mention, from time to time
I have gotten those "code 16" errors on my ECU while driving on the
interstate although my car still seems to run just fine. I was
wondering if that could have anything to do with the sputtering...
(i.e. Incorrect injector pulse) Anywho, I just finished resoldering my
main relay, so I'll report back tomorrow and let y'all know the results.
Thanx a million for everyone's help!

"sputtering" could be bad plug wires,bad distributor cap/rotor,maybe
ignition coil breaking down,a bad igniter module.Maybe even a clogged or
sticking fuel injector,which might explain that trouble code you mentioned
in another post.
But you have to eliminate known problems first(MR),and test one thing at a
time.

"sputtering" could be bad plug wires,bad distributor cap/rotor,maybe
ignition coil breaking down,a bad igniter module.Maybe even a clogged or
sticking fuel injector,which might explain that trouble code you mentioned
in another post.
But you have to eliminate known problems first(MR),and test one thing at a
time.

Distributor cap, plugs, and wires are brand-new, less than 3 months old.
I have an almost-new coil and igniter that I suppose I could
replace. (My distributor has been replaced, and my old distributor that
"died" has the almost-new coil and igniter in it. I left the coil and
igniter that came in the used, but working, distributor that's in my car
now)
UPDATE: Resoldering the main relay did indeed fix the starting problem,
but the sputtering is still present. I will admit it seems not to be
quite as bad. I suppose I need to get a timing light...
Thanx again to everyone for all your help! :-)

P.S. There were 4 cracked dry joints that I had to resolder.
