Hi Sajeev,

I have a confession to make. I may have lied on my last TrueDelta survey. I reported ‘No Repairs,’ but, while technically true, I have been struggling with a problem for a few months now. My 2011 Ford Taurus SHO has been my long distance cruiser for 99,000 miles now, often times pulling an eight-foot trailer full of bikes and gear to track days all over the Southeast. I installed an Airraid cold air intake, Corsa Cat-Back exhaust, and Stage 3 tune from Livernois Motorsports at 17,000 miles, and the car has run fantastic until about 4,000 miles ago.
