Sup people. Ive just bought an '02 r34 sedan and all was good. Recently a whine has started to occur in the timing belt area. Not sure what it is. There is also a misfiring happening. When it idles it seems to run like it has a lumpy cam or something, bout 600-700rpm at the most. When i drive off it sometimes seems to lose some power and not accelerate as fast. It cant go much past about 160km ,when ive had it at the 180km limit. The bad idle and loss of power are all intermitant.
Can someone plz help with my problem, thanks heaps.
