On my way to school last night my pedal stuck to the floor and I couldn't get my truck stopped. When I pull the whole throttle assembly back by hand with the vehicle off to full throttle position it sticks like there is no spring tension pulling it back to idle position. This problem is on a 1994 12v diesel with p7100 injection pump.


Thanks in advance,

 

i had this problem and turned out to be a loose linkage on my 98 12v the linkage has a bend up and a bend doun it is under fuel shutoff my jam nuts on it came loose!

 

Maybe the return springs fell off.
There are two, one inside the other, that run between the power steering pump and the linkage.
Generic springs from an autoparts or hardware store will work.
