I loss power at about 40mph and will not go over 4000 rpm. I had a code of p0172 but it was gone the next time I went out to my car. Still have the problems.

Hello,

The P0172 typically comes up due to fuel related issues.

Possible causes are:
- O2 sensor heater operation
- O2 sensor
- EVAP purge solenoid operation
- O2 signal circuit
- O2 return circuit
- MAP sensor operation
- ECT sensor operation
- Engine mechanical problem
- Fuel filter/pressure regulator
- PCM

Check these article on low power, might help point to the right direction:

I have attached the complete diagnostics for that code.

Please let me know of any questions.

Thank you.
