Over accelerated

Asked by Jan 19, 2016 at 08:50 PM about the 1999 Ford Escort 4 Dr SE Sedan

Question type: Maintenance & Repair

I don't know much about cars or names of
parts but I hope someone can help me
either way, I'll try to explain myself a bit.
The car was over-accelerated, so I tried the
first thing that I knew which is to use the
little screw to control the acceleration, but
the little screw was broken, the tip wasn't
there, so I took that whole part that
connects to the carburator to unscrew the
screw from that bottom and remove it, I did
so and replaced it with another screw of the
exact size, put the whole thing back and
started the car but it was still accelerated
and tried turning it down but came to a point
where the screw wasn't touching that thing
that gets pulled by the acceleration wire, so
clearly I thought the problem had to be
inside. I took out the while piece again, in
the middle there is this opening which air
flows through amd has that metal piece that
opens and closes, follows to the end and
there's a ball bearing there, all of this in
good shape, but finally has an electric
connector. At first I thought it was the RPM
reader maybe, but the car doesn't read the
RPM on the dash board, then I thought that
must be what controls the the acceleration.
I took it apart and surely it is all connected,
from the thing pulled by the wire, to the
metal piece that opens and closes, throuhh
the bearing, and finally connects to that
piece with the shape of a flat head
screwdriver. I moved that piece manually
wondering how it works, and that has to be
what controls it for sure, but I noticed that if
I press the accelerator, the flat head
screwdriver looking part moves a plastic
inside to give it gas electronically, it has
room that when you let go of the gas,
doesn't push the piece plastic part back,
but it should rather place itself back in
position, but I noticed that it barely did, so
something in it must be broken, maybe it
can be replaced? I put everything back
together, used the screw to adjust it, started
the car and it accelerates itself and then
calms down. So to test it out I put it in drive,
no problem, I hit the accelerator a bit and
the car acceletes itself a bit further and
stays at high RPM on 1st gear, I slow down
using the break and little by little it calms
itself. So I go again, let it go to second gear
(Automatic Transmission) and it does
almost the same, I let go of the gas, it stays
accelerated for a few seconds and starts
calming back down, so that little plastic I
mentioned earlier must be taking a bit to get
back into position, some type of spring
mechanism in it that does that must be
broken. Is anything I'm saying making
sense? I can't afford a mechanic who will
take my left leg just for the work. I am just
learning and I really don't know the names
of parts, but it seems to be making sense in
my head. Manual isn't helpful and
searching online has taken me hours and
can't find anything.

Try starting it and then after a min or so quickly press or try to kick it down. Make sure your carpet isn't in the way. Your choke sounds like it's sticky.

Thank you for your answer, but I tried that thinking it could be that the pedal or the line, cable, wire thingy is getting stuck, but I know none of them are, and that cable, wire thingy isn't pulling on it, the problem is somewhere in that carburator area that I tried describing in my question.

Any other suggestions?

Is there any way to repost this?

try replacing your choke thermostat. that was the problem with mine.
