I was driving to the store today with my wife. When the truck started going faster and faster!!! I tried stepping on the gas ( Maybe the peddle was caught on something}. Than I put in neutral and stepped on the brake it skidded out and it stopped finally!!! I found out that the peddle had no tention on it, so I think the cable is off of it. What can cause this to happen and how do you fix it. Im hoping the cable just disengaged and didnt break. Anybodys thoughts would be appreciated!!!

 

Doesn't work that way
The throttle cable(gas pedal) doesn't hold the throttle closed, a spring on the throttle plate holds it closed, the throttle cable pulls the throttle open against the spring's pressure holding it closed

So access the throttle linkage, the spring is a coil type on the throttle plate's rod

It could also be the IAC valve opening all the way, can get engine up to 2,000RPMs

 

I was on a very busy street when this happened yesterday. I couldnt get out and visually see what the problem was, at first. Than I went through the passenger side and I was lifting gas peddle up and down and I noticed the cable wasnt connected to the peddle. The cable was haging down by the emergancy brake peddle. I couldnt get to the throttle body under the hood because of the cover and no tools.

 

The throttle cable comes thru the firewall AT the gas pedal, so no way it could be over by the e-brake cable, its not long enough????

 

You are 100% correct that cable was for the OBD2 plug I have to strap that up. When I got towed yesterday it was free to bring it to there facility. Now I believe the cable was off of the gas peddle. When the tow truck driver picked it up he drove it right up on the bed. The shop was telling me all day it was the throttle body, but couldnt find one for my truck. I think they connected the throttle cable to the peddle to drive it in the shop. I just took that cover off by the throttle body and it looks rusted so I sprayed throttle body cleaner on it now it doesnt feel sticky. But how do you diagnose the throttle body to know if it is defective? Im hoping they said that to make a buck and it went in my favor because they couldnt find the part!!!

 

First, the throttle cable coming off at the gas pedal end would mean the engine would just idle, RPMs could never go up, it would just idle

If the throttle plate(in the throttle body) is sticking then THAT caused the high RPMs of the engine, throttle cable is fine

If shop thinks you need a new throttle body then you probably do, the spring is most likely bad, letting the throttle plate stick open

If it was rusted then it will continue to stick randomly
When it happens again remember you can just turn the key back 1 click to shut off the engine, but don't turn it to far or you will LOCK THE STEERING WHEEL!!!!

 

Thank You for the info!!!

 

I got a reman. from Rock Auto. I took the neg battery cable off, took the intake off. Everything was 8mm. Took the throttle cable off the throttle body, than the 4 8mm bolts to take the throttle body off. I put alligator clips on the neg to the positive to drain any memory in the PCM. Remember to put the hose on the throttle body before you bolt it on, very little room and the belt gets in the way. Put the throttle body, intake hoses and plugs back, and put the Neg battery cable back. I started it and let it run for like 20-30 min. That I took it for a 20 min ride. The check engine light is still off Knock on wood. Remember I was always trying to figure out how to get that off hopefully this is it. Thank You for your HELP!!!
