Cuts out for a split second while accelerating PLEASE HELP!
1998 4 runner 3.4l motor
new parts
Rebuilt motor (prem parts)
new fuel pump
New filter
Changed maf to later model
Plugs/wires
Coil packs
It idles decent maybe a touch rough and it has plenty of power but when I hit the gas it cuts out just for a split second and goes fine the rest of the gears. Like a vuh-ut-roooom haha! I do have a running lean code but I associate that with the new maf, or the crap temporary exhaust I whipped up just so I could get the 02 sensors in (stick welded 😂😂😂😂 maybe this is the issue?? Thanks guys

So after 2 days and one screw it turned out to be the aftermarket air filter I had on, it was too restrictive. That's what I get for going cheap 😂 my word I feel stupid, thanks for the help man!!

Guys,
Please others in the future by telling us which after-market filter you've had problems with so we can avoid them, too. That's what this forum is for; To help people solve their problems and to help others prevent problems.
It could also be bad fuel leading to clogged injectors.
It happened to my Sentra in 1986 - solved with STP fuel injector cleaner.
It also recently happened to my 1986 truck upon leaving the back roads of Utah. Hesitation when accelerating. A few tankfuls of fuel from better sources combined with 2 treatments with FI cleaner and it's fixed.
