  • Corsa 1.2 Vegas Starting Problems 10 Feb 2007 (Forum)
    start! Vauxhall think there may be a problem with injector or ecu message regarding injector as there were previous fault codes but they have been resolved. Usual vauxhall prices £300+ vat no labour for each option. Anybody got any ideas. Seems intermittent and that would suggest electrics? I have

    on completion of the work. We left a bankers draft and drove the car home. We had hardly got a mile from the car lot when the car cut out. Any attempt to give it any throttle would result it cutting out with a bang and the ECU light coming on. (It was ok on the initial testdrive.) It was able to be restarted
  • Nearly new car running very badly 12 May 2005 (Forum)
    this, is a pleasure to drive. No fault codes were stored, so the dealer replaced the ignition module and plugs. No difference. Then the ECU, same again. To get to the point, the car has had 18 dealer visits in its 19 month life. Its had the above replaced, along with every engine-based sensor, but still no joy
  • Doing it yourself!! 10 Jul 2003 (Forum)
    of the things that most of us would, such as check the air filter, fit new plugs and HT leads and look for faults in the fuel system. It was all to no avail. It was suggested that the ECU was to blame and, as you will know, this item is far too expensive to replace in the vague hope that it could be at fault

    . replaced the MAF no change, replaced the boost solenoid on the back of the engine under the pump ecu, no change. The solenoid valve I fitted to the top of the engine that turned out to be the EGR valve, was in fact the rear boost lower solenoid valve, so that was a bonus. The pipe fitting on the old boost

    a signal to and from the ECU too apparently. It's one of those SmartCharge things Ford is adamant is a good thing. He reconnected the alternator and the car's idle went mental, rising to 2.5K and more without touching the accelerator pedal. We disconnected the 3-pin plug so it's now working

    . i have tried to reset the ecu, but it will work better just for about 2 days and then go back again to working horribly. i have been to 5 mechanics . they said the changing of the rims will not cause that, just coincidence. i have changed new fuel filter with regulator. also the fuel pump. we put

    it up with a blow torch. It reads up to 0.8v, but I haven' wired it up in real life to get actual values when the car is running. Should I be overly concerned about the "003) Exhaust engine idle speed too high [7.3.D.2]" as Haynes says this is controlled by the ECU
  • Focus 1.8 TDCi 2001 - 9318 Fault code - occasional engine stop and rough 1 Nov 2012 (Forum)
    (but working) EGF valve. On my car it appears to be attached to the intake manifold so that looks like a tricky  job but if someone can tell me it's easy enough I will do it. Replacing the CAM position sensor and updating ECU software may be a good idea. Any other ideas?  I

    find no faults with the car.  They remapped the ECU and while the (always black) smoke is significantly less than before, it is nevertheless present, particularly on the motorway, with small depressions of the accelerator in 4th and 5th gear.  I cleaned out the existing EGR valve

    Hi, our car has recently developed a problem/ several problems that have stumped us. We've always been a bit conscious that the timing isn't quite as we'd expect it to be, ecu has been reset which solves the problem but only for a few weeks/months.  Last week the car started bunny

    over and the speedo/rev counter went round to 110/5000rpm on starting and all the segment of the mileage display lit up - I assume because of low voltage. I'm wondering if the low voltage as reset the ECU or anything and the car needs 're programming?' which is causing the coughing/knocking noise

  • Car has serious problem - HELP! 27 Jun 2002 (Forum)
    psi after 3000rpm but that would account for up to 50bhp loss! More likely this is a symptom rather than the root cause. IGNITION TIMING: The engine is falsely reading high charge temperatures and retarding the timing. This could be faulty ECU, or sensors. TURBO itself. Does'nt smoke or make a noise
