Title: Sticky pedal
Post by: FirstBird on May 27, 2012, 07:00:56 PM
Anyone have this happen to them? The gas pedal gets stuck all the way down and wont come back up. That just happened to me, so I ran a stop sign. Thank God the guy standing there understood I was in trouble and didn't move. This happens but also it seems like I always have to have my foot on the pedal or speed drops constantly.

I had that happen one time in our 87 TC. I parked the car asap and didnt move again until I figured out why it happened. I dont remember the exact cause but make sure the linkage/spring isnt gummed up or coming in contact with anything.

Yeah I'll check that out, have you also had it basically gradually loose power once you take your foot of the pedal?

I have been having trouble with my floor mat riding forward until the leading edge where its cut to go around the pedal gets to where the pedal is. at that point, I'll floor it for some ricer kid, or just to jerk myself off a little and it will get stuck down. I panic for a second, then I reach down and pull the mat back and it's all good again. Our factory driver's floor mats don't have the hook or pin retainer that the newer cars have, I wish mine did, so I wouldn't have had to take the mat out.

Check for a stretched throttle cable also.

Its more likely your throttle cable is "dry" and needs to be replaced. With how many times that cable moves its suprising how little its changed. I only changed mine due to a new intake setup but I was pleasently suprised when the petal was no longer stiff feeling.

whereabouts can you find a new throttle cable for these cars?

I just shimmed mine. It's almost a guarantee that if you haven't changed your cable or done something to move it up, its stretched. A lot. If you pull your pedal by hand towards the seat, you can see how far out it is. It should be just a little lower than the brake pedal when it's tight. get on your back and look at the top where the cable comes through the top of the pedal and figure out how much you need to shim it and then find something to take up the slack. I used t-splice connectors for 16 wiring. Makes a hell of a difference. As far as it getting stuck, make sure there's nothing blocking your throttle blade inside your throttle body that could cause it to get stuck open.

Just order a trottle cable for a mustang. Firewall forwards and even the pedals should be the same.
I kinked my gas pedal doing an intake swap, and I have also had the tv cable stick. I also once found a small hose clamp holding the tv cable in place work loose, and would sometimes catch the throttle return spring bracket.

I'm pretty sure the 3.8's use different cables than the mustangs/5.0's do. I know for a fact the trans kickdown cable is different.

Didn't even think of that. I was soon to be 302/351 in the sig.
I wonder if a 94 up 3.8 cable would work?
The pedals will bolt in, and the engine/trans layout should be the same.

No one has the ford part number for the Cougar cable? I scoured all over coolcats.
I couldnt even find one listed on the ford parts websites.

Year and engine, please, I'll ask about it in my parts dept. If I know where you live, I may be able to tell you if anyone near you has one.

The Ford PN is E6SZ-9A758-A, but nationwide there are none in stock, you can still google it, though and maybe find one on ebay or something. Alternatively, CA9033 is available from autozone for under $50. The part is 86-88 only.

Here is a part number for the 82-87 3.8 that is in stock. Also list 83-85 2.3 and 5.0, but does not have either in stock. Still working on the 88 3.8, but I have a feeling that the 5.0 cable should work.

After a lot of reading, 94-95 mustang guys use the fox throttle cabble when they get rid of the cruddy 94-95 style intake, but its about a foot too long, but works and functions fine.
I am of the opinion that a 3.8 94-98 cable should work, and that a fox 5.0 will. It just might be a bit long. One way to check, would be to see if the 94-04 v-6 stang guys swap to a 5.0 cable or not if they go to the regular intake.
I spent about 2 hours trying to weed through all the bull that comes up any time you put mustang into a google search, and gave up.
I couldn't even figure out length differances, if any, between the 3.8 and 5.0 motors for 94-95. Its like as soon as mustang in thrown into a product, suddenly noone care about specs or information.
The 84-87 3.8 cable is short, about 20". The turbo coupe 86-87 is 36" and the beloved 86-88 5.0 cable is 30.25-30.65, and near as I can tellb looks the same as the 86-93 nustang cable. However, I could not find a single number for the mustang cable.
I would assume the 3.8 with its similar layout and throttle body location in 88, that the 86-88 5.0 cable should work, but may be slightly too short. If this is the case, the extra 6" of the turbo coupe, or a 94 up 3.8 cable may suffice.
But like I said, could find a single length number for mustang cables.

Hopefully it's not a stretched cable, I checked it and it seemed to be fine it was probably the floor mat like FoeYouknow said, and worst case scenario if it is stretched I now have the info to find a replacement.

The thing that I'm wrried a bout is the connector. As I said before, I know for a fact the kickdown cable is different. We don't have to worry about that connector that breaks and pops off or whatever. I'm thinking the cable may be different for the TB as well. You are probably right that the 94-98 would be the same but I don't think 5.0's will work. But I don't know much about them....
Here is a pic of what the connector looks like and I tried to get it to kind of show how is bolted to the intake bracket too.

Looks identicle on the end of the throttle cable to my. 88 crownvic with the rotated intake. I'm going to be doing some junkyarding this weekend, I'll see if I can get a better idea and pictures. There might even be a sn95 mustang or two.
