Title: Accelerator Pedal
Post by km449 on Aug 27^th, 2005, 5:35pm

My 2.3 97 auto has been feeling a bit sluggish recently, with snatched unintentional kickdowns.

Acceleration seems a bit below par although once up to speed car flows seamlessly

Noticed that the acc pedal has gone how can I describe it - sloppy I guess, with seemingly a lot of slack in it, and it's far from anywhere near the top of its potential engagement point.

Would say that, if assuming the pedal was at the very top of its possible engagement point calling that 100% its down to about 40%.

Appreciate that they have some slack in them anyway but it doesn't feel right just now.

Thoughts/comments/suggestions appreciated.

Thanks, as always, (non mechanical) Keith

Unusually, for the Scorpio !, the accelerator cable is simplicity itself and exactly the same as fitted to any any other car , a single strand of wire inside a hollow cable from the pedal in the footwell to the throttle mechanism. Sounds as though the single strand is either sticking inside the cable or alternatively follow the cable to its anchor point on the throttle quadrant and see if the mechanism moves freely and returns to its start point without sticking. A blast of of WD40 may do the trick.

Thanks for that.

There is some slack at the quadrant where I guess the cable has stretched a little.

It's only about 1/4" but you can see that slight delay in operating the quadrant.

What I couldn't see was how to fractionally adjust the cable so would be grateful as always for advice

Thanks

Keith

I have a similar problem, my scorp is manual but the accelerator cable seems to be longer than it must be.....in WOT (wide open throttle) it only opens the throttle plate about 80 % and i can't figure out how to "make it shorter" a bit.

The accelerator pedal should be slightly lower than the the brake pedal. If you feel that the pedal when hard to the floor isn't opening the throttle fully then it can be adjusted where the throttle cable reaches the quadrant. Pull out the retaining metal pin ( you may need a screwdriver ) then pull the cable out a few millimetres then replace the pin.
