Hello, I have a 2011 malibu that has some odd electrical things going on. Misfires will start and the tac with stop working, As soon as the tac stops working the [engine](/topics-engine-chevy/) will stop missfiring. Could this be due to wire loom on the harness that has rotted away and heat causing issues within the harness? Mechanic's Assistant: Have you checked the coolant level? Has there been any leaking from the hoses? No leaking that I have seen, and coolant level is good. Mechanic's Assistant: Are you fixing your Malibu yourself? What have you tried so far? Fixing myself. I replaced the wire loom that is in front of the motor. all of that was gone. Seems to of fixed most of the issues, but still felt a miss. Looks like the harness loom to the injectors wiring is also bad. Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? Cleaned the mass air flow sensor as well. the engine light came on but after putting the wiring loom on it went off on it's own.
