I have had decrease in power in my 04 Z. It has about 64k miles on the odomoter. There is a slight noise coming from the pulleys like mildly squeeking along with a slight slight faint ticking from engine but might be sound of the VQ cause I know they have the tendency to make that slight ticking. When sitting in my car at idle it idles roughly a little bit every 3 minutes or so almost like maybe a slight misfire not sure. I fear there may be oil on the plugs. I ave a 100k/10yr Warranty. Will Nissan cover this? if so im gonna make my appt for next week.

 

bump...please need some help

 

go to nissan and ask for yourself prolly is ur best bet...can't diagnose something like that over the internet with no sound, or anything..or pics or any info. check ur belts, are they tight, worn down, ?
