Engine Performance problem
2001 Infiniti I30 6 cyl Front Wheel Drive Automatic
First I need to start the car several times so the car will stay running. Then once the car is running it only does 20-30 mph. After about 10 minutes of driving I may be able to reach 40mph. I have to slowly press the gas pedal for the car to move if I floor the pedal I get nothing. I just replaced the fuel pump 8 months ago. Yesterday I replaced the Mas Air Flow sensor and that did not fix the problem either. Any help on this would be great.
