Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. On this engine you need to change the wiring harness for the knock sensors when changing the sensors. It is the only way to ensure trouble free operation If you did replace it then you need to check the connection at the computer. It is located under the hood next to the radiator on the driver side. Make sure that it does not have any corroded connections. Please let me know if you need more help.
