Telboy44 Well after cleaning my throttle body due to slight issues of the tickover dropping and car missing a beat ever so slightly I got my code reader out and it showed faults P1120 and P1220 which is the throttle position sensor if Im right.I cleared the codes and let it see if it throws it up again. Now when I stop at any point with the car the tickover drops down to its normal 700rpm then for a split second every now and then the car seems to cut out as if its going to stop then settles itself down again. Also when you come of the throttle in traffic and come onto the throttle very slightly theres a little misfire for a very split second. Yesterday on a run to Manchester the car would not pull right and was holding back really bad as if it was missing then all of a sudden it would come into life and pull away,at this point my EML light came on so I put the fault code reader on expecting the same codes but its showing P0131 now.I cleared it off and reset the light and the car is ok again now but Im sure the fault will come again as it has before. Can anyone shed some light into what needs changing please
Matt When you cleaned the throttle body, did you remove it from the engine to do so? Another thread with the same fault codes and symptoms: https://z22se.co.uk/threads/zafira-2-2-spluttering-wont-rev-errors-1120-1220.16548/
Telboy44 I have done the carb cleaner test on her and she is not reving up when I squirt it around the throttle body so not showing any leaks.She has the tickover problem everyday but the issues on the holding back and not pulling right started yesterday the cleared themselves.Makes me wonder if a sensors going down somewhere.
MikeS low revs misfire could be egr or front lambda more concerned it could be a faulty throttle body only way to find out is looking at voltages / position % at idle and under load - i.e opcom or enginecheck
Telboy44 Would my little fault code reader do this or is it a tech 2 issue as my mates got a garage I can ask him to check it for me on his machine.Been out today and its ok on running but the little tickover problem was showing itself
