Sluggish when accelerating?

Hello,

The P0171 (system too lean) and P0101 (MAF performance/range) are probably related. I would make sure the catalytic converter is not clogged. Also, check to see if there is a tear in the intake boot between the MAF sensor and throttle body. Here is a guide to help us fix the problem.

and the cat test

Also, check the air filter, if it is clogged it can cause this. Please let me know.

These are the codes that came up. I have cleaned & replaced the MAF sensor & the IAT sensor. I have also to the intake boot (according tube) to see if there was any kind of hole or tear in it & to clean the throttle plate (butterfly). It Idles fine in P, N & Drive. & it mostly drives fine, but sometimes it will stutter/hesitate when pressing the accelerator. (Especially going up a hill)

Thanks for the engine running video, do you hear that click noise it can be the high pressure fuel pump is going out. I would remove the pump for inspection/replacement, also, did you check the cat using the video?

Here is the location for the HPFP.

IF the MAF sensor code is still there after the sensor replacement, I would recheck the cat first.
