Before i go to the garage to get this checked out just wanted to make sure its not my mind playing tricks!

I have a peugeot 206 1.4 2oo2 reg automatic- The first problem i have is that when at a junction sometimes when i accelerate there does not seem to be a lot of power, and then other times no problems!! Not sure if this is an automatic car thing or not!


Secondly, when travailing at 50 mph + there is an odd noise from the engine. Will try my best to describe it- its a bit like the hum of a chopper or maybe a car etc driving along rail way sleepers. I know that's not the best description, but can't really get a better one than that

Going to check the tyre pressure but doubt that is the problem. I did have a mini service done on it by a peugeot dealer after i bought it. Everything checked out fine!!
