Right guys need some advice off you. Picked my car (182) about 4 weeks ago. 900 miles later I've smashed the fog light. No biggy but today all hell seems to have broken loose. First driving down motorway between 70-80ish and the temp gauge starts flicking between hot and cold. Pulled into the services and sat and watched as it danced all over the show. Any ideas what this could be. As I pulled away I noticed a strange rattling sound. Stopped and revved the engine and at 2k revs there is a very noticeable rattle from underneath. Is this similar to the 4k rattle that the 172's suffer from. I had a look round and I can't pin point the exact location but I can hear it. Everytime it passes 2000rpm (up or down the rev range) it rattles. I also noticed that the exhausts pipes seem to emit hot air/gasses from the left pipe and cold only from the right. Is this a design feature or is something the matter? Any advice on the above is appreciated. Any chance all 3 could be related. I've driven the car quickly since i've had it but not ragged the nuts off it and i always warm it up before i go past 5k revs. Not really a great start really.:dapprove:
