i tested my 99 f 150 4.6 and came up with code p0133 which states ho2s sensor or pcm or silicone in my fuel , anyone else have this ever happen . i was driving and i lost power it would only idle .i removed the air filter floored it a few times drove it home 5 miles it ran ok . started it the next day it started and stalled . i got it started race it up afew time then it tripped the engine light .also has code102 +153 help.

Most likely you need to clean your MAF and replace your front O2 sensors.

P0102 indicates you have a fault with the MAF sensor. Inspect the wiring and connector. Reseat or repair if needed. Pull the sensor and inspect the filaments to see if either are broken.

Treat the MAF issue first as it is more critical and may be a contributing factor for both of the O2 sensor codes. A bad MAf will also cause the engine to fall flat on its face. With the power off, disconnect the MAF sensor and see if the engine runs more closely to normal (ignore the CEL that WILL result). If the engine runs well with no MAF in-circuit, then there is a fault with the MAF or its related circuitry.

get some MAF cleaner clean it up really good. get electrcal contact cleaner and clean the plugs and stuff up. and you should be good to go.

A dirty MAF sensor will not cause that code, it's an electrical circuit fault.
