Codes have been done by mechanic shop, oxygen sensor, catalytic converter both new, map sensor new, TBS, new throttle body new, injectors new. Says EVAP system, cannot find diagram for this, and seems clearing codes do not work have same issue.
Thank you.
There is a electronic module? With 2- vacair lines on driver side top of motor no-one can find what it is, it is injuction with fuel EVAP system.

These items are on driver side of motor on top, one on fuel EVAP other is on intake, back side. No identification or numbers to cross reference. All codes run same with New parts oxygen sensors 1 bank and 2, catalytic converters, fuel lines, fuel pump, plugs wires, injectors, still low power light and engine light, if clear as driving runs great fifteen minutes, all lights turn back on. No power.

Good afternoon.

Lets start with the codes. What are the exact code numbers?

As far as the low power, have you checked the compression to be sure the timing belt is in good shape?

Lets run the codes to see what comes up. It sounds like to me this can be a throttle bore issue. Please let me know the codes.
