Customer Question

Cam and Crank sensor correlation code. The engine starts and idles well, no knocking but it will not accelerate. And it throws code for correlation.
JA: Does the vehicle stall at low speeds? Does it sputter?
Customer: No it just won't accelerate
JA: What is the model/year of your GM?
Customer: 04 GMC Envoy
JA: Are you fixing your Envoy yourself? What have you tried so far?
Customer: I am actually trying to help a young lady with 2 kids and a terminally Ill husband that are currently stranded and in a bad way. They are my neighbors and I feel sorry for them and want to help. They have no money because medical bills are taking everything they have and I am not able to pay for them to take it to GM for repairs.
JA: The GM Mechanic's require payment for their services. It's way less expensive on JustAnswer than face-to-face would cost.
Customer: I understand, I am willing to pay just can't afford dealership
JA: When we are ready I'll take you to the appropriate web page.
Customer: All I learned about this was that Derrick the husband changed the Cam position sensor and the Crank position sensor and now he is having these issues
JA: Anything else you want the mechanic to know before I connect you?
Customer: Nope
