2001 honda accord has a code p0172
my 2001 honda accord engine light is on. A mechanic suggested a tune up. the car was not shifting gears properly.I thought it was the transmission.i replaced the spark plugs the wires the rotor and distributor cap,and added a can of seafoam.car still does not shift corrrectly.transmission fluid is clean and no burn smell.light is still on so i took it to auto part store and they gave me the codes p0170,and p0172 which means fuel system to rich!ok so know what do i do any suggestions or answers will be greatly appreciated
Is this a good question?

Same issue here changed fuel pressure regulator, same codes came back, but now is shifting fine after I replaced the knock sensor, but still dealing with p0170 p0172, im checking fuel injectors next.
