1990 Bronco, throttle cable

[GoWest]

I'm a new Bronco owner, 1990 setup for semi serious offroad.

The gas peddle is not what I would call peppy. It goes to the floor but to get it to shift down I really have to lay on the pedal.

I looked at the linkage at the pedal and it has about 3/4" of play in it before the cable even engages. I assume that a new cable is in order because it's stretched or there's a bushing missing.

The linkage on the intake isn't broken, the spring looks good and nothing is loose there. I looked on line for a replacement, there are many and it looks pretty much plug and play. Anything I should be aware of other than that? Thanks

Throttle Valve (TV) Cable pic in a 90 at throttle body

Be aware that any adjustments should be made w/at least a TV Pressure Gauge with Hose T86L-70002-A or equivalent

Throttle Valve (TV) Cable Adjustment & Diagrams; Using a 100 psi pressure gauge to the TV port on transmission

Under normal circumstances, it should not be necessary to alter or readjust the initial setting of the TV control cable. Situations requiring readjustment of the TV control cable include maintenance involving the removal and/or replacement of the throttle body, transmission, or TV cable assembly.

When the TV control cable is properly set, the transmission TV control lever will be at its internal idle stop (lever to rear as far as it will travel) when the throttle body throttle lever is at its idle stop.

At accelerator pedal WOT, the transmission TV control lever will not be at its WOT stop. The wide open throttle position must not be used as a reference point for adjusting the TV control cable.

Cable Removal in an 89 5.0

Walt was replacing ntake, pan valve cover gaskets

two pics for example;



"...The throttle cable is removed by prying upwards at the bracket to remove it and simply prying upward at the throttle body with the same ***** driver..."



"...the tranny cable is removed by pulling towards yourself and lifting up.

At the bracket towards the rear, use a pair of pliers to squeese the retaining clips together, thus allowing you to push the cable through..."

I assume you have an AOD; if so, note how the "tranny Cable" (Throttle Valve (TV) Cable) is attached; snap some pics before beginning job.

Throttle Valve (TV) Cable Adjustment; "...AOD’s use a TV. (throttle valve) linkage on the left side that is hooked to the carburetor or throttle body with a cable or rod. Setting the TV (throttle pressure) cable is a crucial adjustment for the AOD but it’s not hard to do. Normally the cable is set so there’s neither slack or has tension on it in the closed throttle position. With the throttle pushed to wide open, there should be just a little extra movement left in the linkage on the tranny..."

The linkage at the intake end looks good and works fine. My issue is the cable linkage at the foot pedal that doesn't seem right.

I though it was kind of sluggish when I bought it and thought that it might just be a tune up issue but that checked out fine.

My issue is that the foot pedal doesn't engage the actual cable at all for at least the first 3/4" of pressure on the pedal until the slack is made up and I cant get full throttle unless I drive the pedal into the firewall.

The cable has a like a green plastic guide on it that keeps it aligned on the top of the pedal and the cable has a welded bead on the end.

If I could slide the bead up the cable about 3/4" it would take out the slack and provide instant throttle response.

I read about a fix on some site where someone crimped a split shot below the bead to remove the slack but I wonder if thats really a wise idea.

i used zip ties to take up the slack works good use what ever you want just be sure to leave a little slack like 1/8" zip ties, split shot anything that will take up the excess cable. but also keep in mind that the cable is probably stretched and may be ready to snap
