You're right.. it probably didnt.
But I always noted that anytime you fix something under the hood, there is a
ten percent chance somethnng else will immediately go wrong.... even if
you're sure you didnt touch it.
Sounds like engine is flooding, barely running. Raw gas WILL get in oil.
Black smoke out exhause too? FuelPressRegulator leaking?
Maybe Stuck injectors?
And WHY did you change the thermostat in the first place..overheat?
Take that back...MAYBE you did cause that.
If the problem seems to be cumulative, meaning it didnt show at first, - AND
it starts well enough when cold- your engine is maybe not getting up to heat
enough, assuming this is the 1st gen EFI system. Combination of engine
coolant temp sensor marginal.
Your ECU never goes into closed loop and always runs rich... the EGO sensor
never looked at because it's always warming up.
Just a wild guess, like I say and would require some other marginal
There is NO reason to lower the engine temp!
Causes increased oil sludging, and MAYBE what you see there.
my husband is suggesting that I change the whole car over to a carb but I
can't even think of all the work that is in changing the intake and
throttle body right now since I don't have ant other wheels.
That is a terrible idea with an efi car. The car never gets up to
temperature, never goes into closed loop mode, and the computer keep
injecting too much gas becasue it thinks the car is cold. Change the
thermostat back to what it is supposed to be. A 180 degree thermostat wasn't
a good idea with later carbed cars either. Why do you think it is a good
The same reason she thinks a putting a carb on is better than repairing the
EFI system. Lack of knowledge about fuel injection. IIRC that particular
system had problems with the IAT sensor getting full of gunk and causing
rich running. If I were her Id put the right stat back in and clean the air
temp sensor. A better option would be to find a mechanic familiar with older
fords and just let him diagnose and repair it.
We once changed wiper blades for a lady. When she got home she
called and asked what we did to her car that the RR window would
not go up? She insisted it was our fault since we had the car in
the shop. We fixed the window at not cost. I don't know how
many times we gave away free batteries to customers who
it went bad right after we worked on their car even though the
work was not related to the battery. Is is all a cost of doing
business in the modern, it's not my fault world, I guess. LOL

I disagree, once you start giving things away there is no end in sight. I'll
bend over backwards to help a customer with a legitimate complaint, but
anyone who complains to me that a window quit working because I changed the
wiper blades will get nowhere real fast. I could care less if such a person
ever comes back and in fact would prefer not to have to deal with them
again. Life is too short to waste much of it trying to satisfy the .1% of
the public which can best be described as either total idiots or scam
artists looking for something for nothing.
I respect your opinion but after more than fifty years in the
business I believe it is better to oil the squeaking wheel. A one
time investment of less than $50 in good will is money well
spent, IMO. One dissatisfied customer, legitimate or not, will
do one more harm than fifty happy customers will do one good. ;)
I got the car fix with a new fuel sensor and the right thermostat and
keeping my husband away from it Thanks for all the suggestions I just
can't find anyone here in Michigan who knows anything about these old
cars. I think eveyone is just trying to get me to get ride of it beceause
it isn't a popular car.
Yep, the old " you filled up my radiator, now my radio doesn't work. What did
to my car" syndrome.
Last summer I had a lady friend drop off her ~96 Escort for a brake job. She
bought all the parts. I pulled the wheels and found that all of the parts were
I put the wheels back on and went to move the car out of the way. It barely
and ran on ~2 cylinders! I was standing in the diveway when she pulled up, the
running fine then. I had no explanation.
It turns out the motor dropped a valve seat on #1 cyl and sent chunks into the
intake that got into the valves in #3. To this day, she thinks I did something
engine. All I did was turn the key.
We're obviously not dating anymore. :)
Don't think a 180 deg thermostat will let the computer go 'closed loop'.
I'd put back a new 192 (or 195?) thermostat asap... if you lucky, you
won't have to do a catalytic converter as well.
Converting it to a carb will open a Pandora's box the likes you can't
imagine. Not only that, if you live in a state like California, getting
it smog checked in the future will require multiple acts of Congress...
Put in the right thermostat, and enjoy...
