Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
good morning my name ls roy and I will assist
the fly by wire system is failing. there should be a code stored for this in the computer. there is a throttle position sensor on the throttle body that is common for failing, pedal sensor and wiring.the code will help lead us to the area of failure. a parts store will pull the code for you fro free.
the reason why it is ok at times is it re sets itself every time you turn off the car and re start it.
ask them to read the code for you. I would not buy any parts until we determine the failure
we need to get the code,otherwise it is just a guess and they can get expensive.
try calling other stores and ask if they can read history codes
how are you making out
