The throttle position sensor has an idle switch in it that tells the car's computer that the throttle is positioned at idle. If the idle switch sticks in the idle position, the computer will not allow the engine to rev more than 2500 rpm. In your case, I think the switch is stuck.

First, see if you can get the trouble codes to come up. Rig a jumper wire and jump between the "T" terminal and the "E1" terminal in the car's "Diagnostics" box. It is a small black box on the driver's side of the engine compartment near the battery. Open the lid and on the inside of the lid it has a map of the terminals.

Once you hook up the jumper wire, turn the ignition switch to on but do not start the car. If there are codes, the check engine light (orange) will blink the 2 digit code. It blinks the first digit, pauses, then blinks the second digit. The code for the throttle position sensor is code "41". That is, four blinks...pause...then one blink. If this code comes up, change the throttle position sensor. (If there are no codes, the check engine light will steadily blink once per second until you turn the key to off.) Don't forget to remove the jumper wire when you are finished.

poss bad earth, check ecu supply when then cranking. if not you need an oscilliscope to see what is up with signal on crank sensor, some vehicles power cable is so close the noise from it wipes the signal same as a bad starter it interfers with the signal, (noise is the magnetic fields)
