My new 172 smells like its burning even after short runs and its only done 1600 miles!! Is this maybe the cat burning in?? I had a terrible smell from the cat of my saxo vtr for a few thousand miles until it was ran in. I did try to run it in properly although I admit to the odd thrash especially as my mates just got a cup and the inevitable race happens occasionally (no difference in performance noticable without wanting to kick off another topic). Ive checked oil level and coolant levels and everything seems o.k. What should I do?? Bought the car last month and its an import, cant be arsed with hassleing my local main dealer if its something daft, any ideas or advice??
