Starting there might help you

 

I'd lean towards the O2 sensor going bad. Intake leaks might be easy to check off the list. THe next one down as a possible cause is the 02 sensor. Not a big deal but you have to get creative with some hand tools to replace usually. 02 sensor socket plus some channel locks or adjustable wrench should be enough.

 

I know this isn't the same code, but when I got a P0170 code on my 95 max (similar to your P0171, both fuel system malfunctions) it was my O2 sensor that broke (well the mechanic did putting a bead on it for some unknown reason). I got it replaced and the code went away.

 

I will be changing my oxygen sensor today , hopefully if i can get it out on my driveway , bank one sensor 1 , hopefully this will solve my problem . if not i will report back

 

how long till the o2 is ready ? my heater is ready but not the 02 or the catalyst or evap , i need one more ready monitor to pass inspection ,
