Alright all my Nissan family,

I'm in dire need of your help and advice. After 151,000 miles, my car is dying.

I was driving home from work today, when my car went from a nice, sweet, sports car sound, to sounding like a Subaru STI with a 3 inch cat back exhaust, and blue smoke billowing out from my 2.5 inch, Magnaflow cat back exhaust.

Every time I stopped at a light, the RPM's would dip to about 300 RPM and shoot back up to about 800 RPM's.

I have also lost power, engine response had gone down, and top-end power has suffered as well.

Please help! What could be wrong with my precious??
