Hello everyone - I recently purchased a 2014 Sport. It was a good deal and I paid cash for it. It has around 180k and I knew I would be taking risk, as with any vehicles with high miles. I've noticed that when I accelerate, it falls flat over half throttle. Comparing this to my recently lost 2015 Expedition 3.5, due to a girl running a red light, I would expect a lot more. It has the check engine light so I hooked it up and got the 0299 and 0430 in this order on the device. I have a few things to take a look at before I start replacing anything. I need to make sure my downpipes are tight. Actually had this problem with my 2015 with some loose fittings causing the 0299 code. But the 0430 code is making me think it definitely needs a new cat. Could the codes be related? Meaning, could a bad cat cause the turbo underboost or could a bad turbo cause the cat code? Any thoughts?
