02’ Tacoma engine sputtering

02’ toyota tacoma

new engine, MAF, Injectors, spark plugs, and all belts.

Engine sputters or “2 steps” when accelerator is floored getting onto HWY.
Check engine light is on for a P0172

any ideas?

 

Plug wires could be the issue. Check it in a dark place, if you watch closely you might see a spark. They’re bad for the plug wires shorting out against the top of the valve cover.
Lmk if this helps.

 

Coil packs/plug wires

 

plugs and coils packs are around a year old. I will replace today and see if that was the issue.

 

I bet wires are the issue. I have had your situation twice over twenty years with my truck. Both times it was the wires

 

Coil wires replaced and still missing when under heavy throttle
*UPDATE*
Truck got out of shop and they are stating that I have 20psi more fuel than i’m supposed to and that’s causing the code P0172.
