Default The fix for hesistation during warmup of older Camrys

I wrote this as a followup in a thread above, but decided it is useful and
important enough for a new thread. Anyone with an older Camry is likely
to have to deal with this sooner or later, and may spend big bucks
unnecessarily.

The Problem:
Here's a classic story with older Camrys. The car starts fine and may run
okay for a few minutes. But then as it starts to warm up, it begins
hesitating on acceleration and/or stalling at stoplights. When it is fully
warmed up the behavior goes away. The problem is usually worse after a
rain or in humid weather. Once it starts happening, it gets more and more
severe rather quickly. This one baffles mechanics, who often wind up
replacing a series of expensive parts, all to no avail. Ironically, the
true fix is very easy and cheap.

The Cause:
'90 Camrys (as well as several years before and several years after-I'm not
sure of the exact range of years) have the coil inside the distributor-a
bad idea. I don't know when they stopped doing that. When the engine
starts, it exudes moisture (a product of combustion). The moisture
condenses on all surfaces inside the distributor. That's okay when the car
is newish, because distilled water doesn't conduct electricity. But when
the car is older it has a fine film of debri coating all surfaces. When
those surfaces get wet they conduct electricity and the primary coil shorts
out. Then when the car fully warms up, the sufaces dry and the car runs
fine again.

The Fix:
Use isopropyl alcohol (rubbing alcohol) and cotton balls or
Q-tips to clean all the surfaces inside the distributor. Take off the
distributor cap and the black plastic shroud that covers the coil (snaps
off and snaps back on). Clean everything with liberal amounts of alcohol.
Don't worry if it drips all over-it drys without harm. Don't be
discouraged if you don't see a lot of dirt on the cotton, were' talking
trace amounts here. Give special attention to the coil wires. Also clean
the inside and outside of the distributor cap while you're at it. You'll
be amazed. You'll have to do this every couple of years now.

Hi Mark,
Hard to tell whether you're giving me the business for sounding like a
know-it-all, or whether you just put some extra personality into that post.

Regarding the window, the problem has to be friction or misallignment
somewhere in the system. But a motor that runs at all is unlikely to have
anything wrong with it except bearing wear, and it's also unlikely that it
would have enough bearing wear to cause significant misallignment with
mating parts unless your dog has been constantly rolling it up and down
over the years when she wasn't rolling in shit. So I'd look elsewhere.

This is extremely useful! I already posted a question about this problem on
this ng many months ago, but never had any answer...

I think we have this problem ('92, 280000km) since about a year or so. I
once mentioned it to the mechanic at the Toyota dealer, but he didn't know
what it could mean. We only have this problem when the car hasn't been
driven for a few days. The problem isn't very bad in our case, after about
2/3 miles at most everything's fine, and it really doesn't happen very
often. But, as you said, it could worsen, and then it will be very nice to
be able to point the mechanic in the right direction...

Thanks a lot!

Luc K

Clearly your dog is desperately trying to make himself sexually
unattractive to you. Leave him alone.
