2 years trying to figure this out. Mechanics, Forums, Google ect ect .. No luck ! Thought it was the CVT transmission. NOPE !! I ran the codes on a Reinke Dink 7.00 reader someone gave me and it read a P0151 and P0154. Researched Youtube. Lean Condition is the issue. So for the second time I checked the air hoses around the Mass Air flow Sensor. I pushed up under the 3-4 inch fresh air intake hose Into the ribbed creases of the Jose and my fingers slipped inside the hose. There it was. About a 3 1/2 inch rip. Autozone $91.00 Fresh Air intake hose. Runs like a dream !!! Took 10 mins to change !! Hope this helps others with their never ending search !!
