    Still getting Jerking

    I am still experiencing jerking when off throttle in say 4th gear . It is worse when cold but still evident when warmed up . I have fit a brand new EGR but still no better and tried another Throttle Body (no change) . I am going to try another Coil Pack at weekend , but am starting to think about Coolant Temp Sensor or even Thermostat , car is a 1.6 16valve 2002 with 59K on the clock .

    I am also thinking about MAP sensor causing it too , any help appreciated guys cheers Chris .

    Just for the sake of argument get into Tesco and stick some 99ron super-unleaded in...!

    Could make some difference - did with mine!

    There was never an EGR code stored , put some 99 unleaded in today and a new set of plugs with a different coil pack but still the same . Doing my head in now !!!

    Standard Airbox and filter mate , cam belt done at 45000 miles with new tensioners and water pump . I feel it is running lean so when off throttle (which is idle) it aint getting enough fuel causing the jerking . Question is what is making it run lean? It is either a sensor or is the fuel pump pressure lower than it should be ?
