My Toyota Quantum 2.7GL idles but does not rev up. i ve changed the fuel pump and filter but still it starts, idles but does not rev up when you press the accelerator?
We do not have this model in US, but I assume it is a new model 2016-17. You throttle (and the "rev" ) is controlled by the computer. The fact that your car is idles - should mean that your computer is fine! There are two types of idle control: 1st- when you have a bypass of the throttle, which lets the throttle flop stay close while idling and let's the air into the motor through a bypass and electronically controlled idle switch. Inspect your throttle - the electronic/metal unit located on the large pipe through which the air gets into the motor: if you have a "bypass" for the air then you need to inspect your throttle body as it could be your problem.
2. most likely you do not have a bypass and your idle is controlled by your throttle body, then it is sure working fine and your only issue is that your engine computer does not know that you press the accelerator. Your gas pedal has an electrical unit on it which connects to the engine computer- inspect the connector/wires if all looks fine most likely your accelerator sensor does not work- you need to change the gas pedal unit ( I think it called accelerator sensor).
