HI all, my trusted 2.2 direct engine has 3 fault codes and Im not sure were to begin. Ive looked up and may are saying the fuel pump and regulator need replacing but I thought Id check on here first.
My car just went into limp home mode/engine light on after 45mins of driving. If i switch the car off and restart it drives ok, but after a few seconds the lights come back on
The codes are
P0130, no plausibility between o2 sensor 1 and bank1 and same on o2 2.
P1191-5a, fuel rail pressure sensor circuit low.
P0303-01, cylinder 3 misfire detected.
The car had a full service about 6 months ago, (new fuel filter and plugs). do you think its just a spark plug failure? And how do you test a spark plug if so?
Thanks in advance.
