2004 4.6 triton 2 valve ford f150 155,000 miles when the check engine light initially came on the codes were P0174, P0306 and P0306 replaced MAF sensor cel went off couple of days then gave the above mentioned code P0506
You probably have a bad coil on number 6 cylinder
P0306 is a misfire on cylinder #6 P0174 is a lean code for bank 2 ,P0506

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.

The intake manifold gaskets need replacement as well as the o-rings inside - if you call FORD they should be able to get you the correct parts.

no such thing as a catalytic computer... there is a catalytic converter ... part of the exhaust system so they may now be "guessing" that it's an O2 sensor. take the car to autozone... they will scan the codes for free.... post the codes here tho the lads and lasses there are pretty clever and will probably tell you what the codes mean.
SOURCE: Check Engine Light comes on and off w/ P0304 code
this may be a defective fuel injector or a defective PCM (powertrain control module).
SOURCE: Code P0174 05 Corolla
I don't show any po174 for an 05 corolla. But I do show a po741, if thats the code you're getting.
It means theres a problem with the torque converter
clutch system. It could be the tcc solenoid. Either way, it's related to what you just had done.
Good luck.
