So I was sitting in my car for about 40 minutes then all of a sudden it feels like it's shaking and I notice the rpms are at 500. So I took it for a drive and at a turn light it felt almost as if it wanted to die. Do not have my diagnostic scanner with me. Any idea what could be culprit, all fluid levels are good.

 

Had nothing for active codes. Only thing in history was feul lean bank 1 and 2, no recorded missfires so im stumped. Feul economy is dog **** and it is starting to feel sluggish.

 

Just cross referenced my scaner against my other one. My innova is indication air o2 and cat all in red during live scan, where as my autel shop scanner does not throw any codes.
