Acceleration with 4Runner Failure 5VZ Motor

Hello friends, it happens to me that the engine starts perfectly but when accelerating it stays as if it does not have enough fuel already changes the gasoline filter the air of the chek engine is off and the engine is fine in low but when accelerating it has a flame and I have no diagnostic device, I hope someone me can help thanks in advance ok greetings.

One of the failures can be the TPS or butterfly position sensor, if you have the possibility to check it discard it can be something else but from what you say, discard injectors also, position sensors or also called captors (crankshaft cam) If they are well check the metals that captures sometimes they have oxide today that cause bad readings I hope it serves you

Hello friend:
Your fault sounds like a low fuel prection, if you have how to measure it, it can also be MAP MAL or TPC sensor.

Just as you paint the whole face of being a coil, but Pruba cleaning the flow, with respect to the coil disconnects the cables with the engine walking the stream of the jumped from the strong and blue cable to the spuhcar as the spark jumps, test and avisans.

I look like two things or air flow sensor or covered air filter can also be fuel pressure or some obstructed or apalstada pipe
