Xterra hesitation under load 2-3k rpm

[smokey_the_xterra]

Hello fellow xterra owners! Having a problem with my 05 SE 200k miles, when car is completely warm and I accelerate between 2-3k rpm it hesitates and the engine feels like it’s missing. I have no check engine light, engine temp is around 197-203 when this happens, trans temp is normal around 160-180
(bypassed the trans cooler to prevent smod years ago)
I do notice the battery volts fluctuate about .5 volts.
The vehicle also feels a little sluggish when this occurs

First thing to try is clean your MAF and reset your AFR tables.

Also, spend some time looking over the vacuum hoses for any leaks.

Smoke tested the ole girl yesterday and no leaks! Maf seems to also be fine I’ll look into the AFR tables, maybe a sensor is freaking out lol
