Throttle slack fix.

My 2004 Ranger had about 1/4" of slack. It runs much better now that I took the slack. Now I have true WOT, no more "detatched" throttle feeling, and much better throttle response.

I learned from a member of another forum that there is sometimes slack in the trottle cable on the 4.0 SOHC that will prevent it from getting full throttle and hamper throttle response. Well, my new 4.0 Ranger (I have had for about 2 weeks now) had a sort of "detatched" feeling to the throttle. I.E. it seemed you had to push down on the throttle a little more than need be to get her rolling. So I checked my throttle body and I wasn't getting full throttle. There was about 1/4" of slack in the throttle cable when measured back at the pedal (and it was very noticable at the throttle body too). So I did what the gentleman who told me about this did and used simple zip-ties to take up the slack (while leaving a little in to keep from stressing the throttle cable and the throttle body). Now I have WOT, and the throttle response is GREATLY improved. More hp too? Who knows, but it sure is nice to have WOT (and yes it does come-on much better when you put the pedal to WOT :) ).

Sorry about the terrible pics (I couldn't fit under the dash enough to get a good pic with light, etc. But you get the idea.

What I did was take a crimp type eye connector, cut the eye off, remove the plastic insulation, open the end up enough to slip over the cable & re-crimped. It only removed about a 1/4" of slack but was enough to make full throttle.

Well, when pushing down on the pedal it takes less pedal now, seemed like before I had to push the pedal down half way for the truck to move. As far as full throttle get up & go I can't really tell.

It should work on anything with a throttle cable be it 3.0-4.0, 4-6-8 Cyl, or EFI-Carb it should work if you have slack in the throttle cable.

Good idea. What gauge eye connector did you use?

Nice. I'll have to fire up the lathe/mill in my garage and try this. I was going to eventually do something better than the zip ties, but have not had time to try it. I like all of your ideas. Keep 'em coming.

My spacer took up a little under 1/2" slack. I was needing it bad. I have noticed better acceleration as well as driveability. It helps when your gas pedal doesn't hit the floor

Did it and a huge difference just in passing other cars, not near the Foot to the floor as I use to need!

This is a good mod, especially since there is no factory adjuster to adjust the slack. One small word of warning - it is possible to overdo it. Just take out what you need to get the throttle to open fully when floored, no more. You can put a tremendous load on that small cable if the throttle arm hits the stop before the pedal hits the floor. A few owners have broken cables after the mod, 4.0L's in particular.

i did this a few months ago, but i used a scotchlok and put a wiretie over it so it wont pop off.
it made it sooo much better.. plus i have rubber floor mats..
but my pedal was laying on the mat before i did it.. so i never had WOT..
to old cables.
