At first the only problem I had was the shifter would not allow me to take it out of park unless the release button was pushed, this comes and goes. Then it started taking longer to shift from gear to gear, this comes and goes. I have codes po498, 61-1, po141, po122. I know that po141 is an o2 sensor bank 1 and 2. I have checked my battery terminals and all is well for 61-1. I don't know what po498 is other than evap emission valve control. And po122 is something about the throttle positioning sensor. My gas mileage has dropped by 10 mpg. What should I do? Are these all separate problems or are they related?

They may be related, check your fuel pressure as well as that may be giving some codes. Like O2 sensor. Have the evap system smoke tested to see where the leak is, may be the valve/solenoid. Try cleaning throttle plate on both sides and iac hole with choke cleaner tha tmay help with tps sensor.
