my Vauxhall zafira has started making a chugging noise and is struggling to move I did have a fault code for a camshaft position sensor which I have not had fitted yet but now its making this noise I did another diagnostic check and its given me 4 other codes po120,p0303,p1120,p1550 can anyone tell me what these mean and if they are big problems
thankyou

P0120 is throttle position sensor,p0303 is cylinder three misfire,you may be better getting a mechanic to physically check the vehicle as some of these codes are obviously generated as a consequence of another and are only a starting guide to diagnostic,s and a look at scrolling values would be one of the next step,s,just with so many codes it,s difficult to direct anyone other than to a professional with the equipment to fix it.

had a very similar problem with my zafira last month and had three different sensor's changed including my camshaft position sensor and after £750 turns out my Catalytic Converter was blocked and needed changing if this help's at all??

thankyou I have taken it to the garage and they are going to start with the coil pack for the misfire and the camshaft position sensor and hopefully that will stop the other fault codes firing out
