Hello all. My sisters 04 Santa Fe 3.5 6 cylinder with 150,000 plus miles has a misfire code of P0300 P0303 P0306. She claims that the car looses power about 40 mph and when she lays off the accelerator then applies the accelerator things returns to normal. The car is new to her and has had a new timing belt, plug wires, crank position sensor one new coil for 3/6. So far to try and diagnose the issue I have swapped the 3/6 coil which is new with the used coil from 4/1 and get the same misfire codes. I replaced all 6 plugs and receive the same codes. I swapped the #6 fuel injector with the #4 fuel injector and get the same codes. Any ideas on what to look at next? Thanks for your help
