Randomly sticking throttle - '93 E150

[wirelessengineer]

3 trips to the shop, including a replaced throttle body and throttle cables, and it still sticks whenever it feels like it. Hot weather or freezing, engine cold or hot. Most times shutting down and letting it sit for a while will cure it....

Until it happens again. That may be days or weeks later. Sometimes it's after accelerating from a stop - classic stuck throttle symptom. Sometimes it's on start-up before I even press on the gas pedal - NOT classic stuck throttle symptom! Sometimes it's mild, sometimes it's wild. Last weekend (in snow) it put me up on the sidewalk when I tried to park!

Any ideas?

Nope, I changed multiple parts on mine, tps, egr, water sensors, and I still get the same thing to happen on my '94!! Please let me know if you came up with a solution!!

Well, I DID find a temporary solution. I rigged a short piece of 5/32" stainless cable from the throttle body to run through the doghouse where the driver can reach it. Made a loop on the end, so when the throttle sticks, it can be manually pulled back down. It works.

However, since doing that, I've found a permanent solution:

Scrap the car.

The brake lines rusted out, and given the badly rusted condition of the underside, repair would cost more than it's worth. Too many parts rusted together, making ANY repair a major job, and no guarantee that something else major won't break next week.


So, anybody want to buy parts from a 94 Econoline?
