Power Loss

[LegacyRisk]

My 2013 Genesis with 131K is experiencing off and on power loss, I was told hat the throttle by wire system was keeping it under 2000 rpm to protect itself. And that the timing belt and or tensors are going I'm getting a check Engine Light (CEL) code has several meanings from cam position sensor to timing belt. At times it runs good at others it takes block to get up to speed. It will slowly gain speed to above freeway speeds. I can't afford the timing belt repair if that is the problem Ive just replaced the cam pos. sensor and high pressure fuel pump. any suggestions ? It's a 2015 3.8 lt. 8 speed automatic

I had a similar problem with my 2012 Gen.1 Genesis. Although the cause was never fully explained, the dealer I went to ended up c;leaning the Mass Airflow Sensor (MAF) and that cured the problem.
