Code P1744

2001 Lincoln cont. Misses at 2000 rpm under load but never any trouble codes show up. Have replaced all cop units, plugs, fuel pump, filter, throttle position sensor and cats. Could the o2 sensors be going bad? Mileage is 150000. Or torque converter losing pressure?

Have replaced all cop units, plugs, fuel pump, filter, throttle position sensor and cats. Could the O2 sensor be going bad? Or torque converter slipping? Code P1744 did show up once. It seems like jerking motion at 40 to 60 mph. It seems okay til the engine heats up. In neutral the engine runs great. Thanks, great site!
