I have an 04 Santa Fe that ran great. One day going up a big mountain @ 55 mph it spit & sputtered & dropped to 25 mph. Since, then it has not ran right. It feels like I'm driving a 4cyl. What it does now is driving a long @ 55 mph & try to accelerate the engine revs to 4000 rpm's & mph stays the same. I even had the gas pedel to the floor & the rpms went up & the engine made noise but the speed remained the same. The check engine light is not on & is not producing any codes. Have checked the air filter - clean, air hoses - all tight. Please help, thank you
have the same problem?
