there is a very fast clicking type noise coming form the engine when i accelerate to about 3k rpm, it gets faster and faster the higher i go and is most severe when its cold. could this be linked to the bad cv joints on my wheels? they also make a clunking noise when i coast. also the idle sound sounds very strange, theres a "sucking air" type of noise and also a slight clicking noise. i have tried using the highest octane rating fuel i can get but it hasnt changed anything.
does anyone have any idea what is wrong with my car?
