Hi, looking for advise as don't want to be paying out for unnecessary parts, would rather fix myself but if needs be it will need to go into garage.
While driving home on motorway the engine response didn't seem the same and car felt judder, when slowing down to take next junction the engine management light came on and wouldn't go above 1500 rpm, I have checked the fault code on my phone using an obd adapter, the code was P1120, need help to determine if it the pedalh, throttle body, ecu as can't seem to find a definitive answer online, many thanks in advance.
