Hello all, I need help diagnosing my 94 1fz. Over the past couple days while driving around 2k rpm, the engine would “cut out” and I would lose power. The engine would not stall but the vehicle would jolt forward then no power was being delivered to the wheels. While this is happening, the engine would not be very responsive to the accelerator and was unable increase in RPM. I would then pull over to the shoulder, put the car in park, wait a second then resume driving like nothing happened. It has done this a few more times and then snaps out of it. I have read some other forums about this possibly being a fuel delivery issue like a clogged/collapsing fuel filter or even a failing fuel pump. It’s odd though because my engine does not struggle to reach 5k rpm occasionally. It is very random when the engine decides to “cut out”. I bought my truck about 2 months ago and have done most of the preventative maintenance on it. The previous owner owned it for 4 years and only put 604 miles on it so it has been sitting for a very long time. Thanks in advance!

Cleaned IAC/throttle body, new cap, rotor, spark plugs & wires, new alternator, changed all fluids, new battery, pair valve delete with new o2 sensors in its place, new vacuum lines, refresh coolant, air filter, a couple other things but I can’t think of them now.
