Is there any check engine light on, if so that would tell a story. Make sure the Check Engine Light comes on when the ignition key is turned on in case any one disconnected it, it should go out once the engine starts. Even if the light is off a professional grade scan tool will read live sensor data of key sensors engine vacuum, air fuel ratio air flow into the engine, perhaps the air flow meter doesn't read correct amount of air entering engine (could try cleaning it with CRC product # 05110) .
Best have it checked by someone with scan tool that has Toyota enhanced capabilities. May also need to check engine fuel pressure see if pump is failing.

the check engine light works, but it doesn't come on , and also where do you check the fuel pressure, where is the fuel pressure fitting located? Thanks much

The fuel pressure regulator is found inside the gas tank along with the fuel filter and fuel pump. I know because I'm having the same problems and I'm in the process of resolving them. Before you buy any parts obviously check the fuel pressure tester and disconnect the fuel line to see if that's really the problem. Good luck.

Did the fuel pressure test correct the problem? Right now I can only get the rpm up to 4500 in second gear on my 01 mr2. The car just does not want to move, there is no check engine light. I know that the light works. My mechanic is at a loss, timing is good. New plugs,mass air sensor and oil change.
