Sorry if this is posted in the wrong section, im new. I have a 207 1.4vti 2008. It is very low on power (All the time), doesn't like between 2500 and 3000 revs, wont rev above 5000 revs. I have the occasional fault code for misfire, and did have a code for cam sensor occasionally (Even after it was replaced). I also get O2 sensor fault sometimes. I have replaced the coolant temp sensor (For the ECU, not the gauge), MAP sensor. Ive also done plugs and 2 coils recently. My Bosch diagnostic tool is telling me that the actual throttle valve is only moving 6 degrees, where it wants to be around 150 degrees, and that on the throttle valve potentiometer i have around 500V!!!! where can it get 500V from??? This could be that my machine is reading it wrong, as i have no idea where that sort of voltage could come from (Apart from ignition coil). I have no idea where to go next, what do i do???? Any common faults i have overlooked? Any help greatly appreciated!!!
