Hey Scotty!!! My car is doing some serious exhaust burning when idling, and sometime the temp gauge goes up to 1 more bar but never goes red or overheating , goes back to normal when I'm driving

It's an 05 chevy Malibu v6 some people say they're just like that, and the rpm gauge is going up and down a little, not rough not lean

sounds like engine is wearing out, but do test cooling fan operation
