After my car warms up I don't seem to have mid range power. When I give the car a little gas to get up a hill or speed up it doesn't want to go. When I floor it it goes very well. The fuel pressure checks out. A new fuel pump was installed and a new fuel filter. There are no fault lights or codes. I did notce that the temperature gauge is low. I changed the thermostat and temperature sensor but it didn't fix the problem.
