I keep getting the code 77 in my EEC-IV for an "Operator error during Dynamic Response Test/Wide Open Throttle not sensed". For some reason the computer is not sensing the throttle "goose" that I give it when I accessing the computer for codes. Any ideas on remedies/theories?

 

Throttle position sensor? Or try it again, being sure to push the pedal all the way to the floor, and hold it for just a second this time? Or, check the throttle cable for slack, and maybe do the zip tie throttle cable mod.

 

Not sure what the zip tie throttle cable mod is.

 

Linky to a thread with other linkys.

 

I went to check for slack in my pedal. It is REALLY loose. I will try the zip-tie mod and see if it solves the problem.

 

Did not solve the problem. In fact, it gave me a code 12 "RPM at idle out of range/high" along with the original. So... anyone else?
