Exhaust leak, p0171,0174 codes
#11
A drop at the service port only tells you that there is a leak somewhere in the system, it does not tell you where the leak is. What was the pressure and leakdown at the fuel filter? Those readings, along with the service port readings, will tell where the leak is. Without both sets of readings, you're guessing, and guessing can get expensive

I did have that information too and did follow everything, my mistake. Ive done so much work on her lately that it makes my head spin at times. After the front end rebuild, the engine removal and repair and now fighting the codes Ive had my fill lol.
