The main problem is lack of power and at one time it wold stall at a stop....Now it will not pass 3000rpm while driving. Recently had the Transmission flushed and did not help the problem. The codes i have been researching are: P0733, P1140, P0731, P0171, P0174...so far i have narrowed the codes to the mass air flow sensor, O2 sensor and could use some help with the others. Any help would be appreciated....
