Question about 1996 Ford Explorer
If the front oxygen sensors have over 100,000 miles
on them change & then work on vacuum leaks in exhaust
prior to converter & then ignition misfires
Spark Plugs--every 3 years
Clean MAF Sensor
Exhaust Converter may be shot,then only last 12 to 14 years
If so-- then do the rear sensors as well

SOURCE: Code #P0171 & code #P0174
The most common problem on a Ford with these codes is deteriorated PCV hoses. Check the hoses from the PCV valve to the intake manifold. Pay special attention to the rubber elbows. They often crack on the inside curve and the crack is hard to see.

it may be a defective O2 sensor here is th difinition:
P0133 - Heated Oxygen Sensor (HO2S) Slow Response Bank 1 Sensor 1 , this is the sensor on the side of the engine that #1 cylinder is on, it is the sensor before the cat.

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.

I have a ford 2003 windstar that was running very rough when cold and almost stalling. engine light came on. went to autozone and they read the codes for free and told me it was running lean on Bank 2 also. i came home searched for the O2 front sensors online using the info autozone gave me. there are 2 front sensors on my car that need to be replaced at the same time. look for ones that have a direct plug in and don't need wire splicing. the ones without the wiring harness are cheaper but more of a pain, i think.
they were fairly easy to replace. getting access with the wrench was the worst. reset the light by disconnecting the battery for a few minutes. seems fine now and the light hasn't come back on.
