Cold start problem on '93 Accord

Tegger,
Thanks for posting the pics and the info. I will look into the
motorvac service.

I still had the cold start problem this morning. Would a leaky
injector cause the cold start issue?

The plugs in the pic are a few months old. The last time the car was
on a long run was the end of October for 120 miles. I drive it every
day that it starts, including 15 miles of 60+mph.

Here's a kicker for you: Yesterday when I was basking in the glory of
having my car running again, the D4 light started flashing and I seemed
to lose 1st and 4th gear. We jumped the service connector and the CEL
flashed a code 15. Does the D4 light flash a code too? I drove it
later and no light, no trans prob. I might be ready to toss in my keys!

 

==================================

A cold start issue that _only_ ever appears after the vehicle sits for
about ten hours is usually a flooded engine, caused by a dribbling
injector. The Owner's manual tells us how to start a flooded Honda, and
injector cleaner or Gasohol often cures it it in the long run.

My Odyssey did it to me and had me totally stumped. I never would have
believed my Honda could be flooded all by itself after sitting in the
garage overnight. :-(

Very likely given the condition of that black plug.

Still, something's very wrong with an injector.

This usually happens to trannies that have not had their fluid changed in a
long time (certain parts are stuck). I'd give details on how to determine
the code behind the D4 light, but at this point, just bring it to a Honda
dealer. Your car has had poor maintenance over the years and is now feeling
the effects.

 

or a dead plug. those delcos are not very good. replace them with oem
ngk or densos - they'll last ages and keep on firing reliably long after
they're melted stubs of meteorite.

doesn't matter. replace anyway. look into the injector thing as well,
but crappy plugs can send you on a wild goose chase and new ones are too
cheap to bother /not/ replacing.

change fluid. if problem recurs, it's unrelated to the above. if it's
the transmission control unit, you can get them from junk yards for ~$50
or less.

 

Thanks, guys. I really appreciate all of your help!

I did replace the plugs, as I posted earlier, and they were NGKs so I
should be good in regard to that.

For now I will tackle the leaky injector and trans fluid. Hopefully
once I take care of those things I will have my good ol' Honda back!
