    Default Please help

    OK guys I need your help and input

    Why? because mechanics don’t know and I cannot afford to buy another car.

    1.8xe, 52, club, saloon.

    The present situation is that it will not idle, therefore impossible to drive. The census is that it is starved of air and that the throttle body needs replacing. It runs slightly better with the air pipe off and quite a bit better with the evaporative emission pipe off allowing more air in, the idle revs can be regulated by restricting air pull through this inlet, at which point the engine runs smooth. There are no stored or live fault codes stored; when I left the garage.

    I have had the car back from the garage because of money i.e. their mounting labour charges for investigation. So I have got to do it myself!

    I drove the car back (not far) with the EEC pipe off and I have checked for codes and got P0100 (Mass or volume airflow malfunction) but because I had the pipe off and it did not show up on a mobile tech I am unsure if this is a true fault. I really need to try out a known good one!

    The EGR is now blanked completely so is out of the equation.

    It as had

    Top end rebuild/refurb (skimmed, 16 valves etc) – the cylinder pressure has been checked and was fine and even across all, I do not know the figures.

    New cambelt – rechecked and fully inline

    New plugs, coil pk, air filter, oil and oil filter (rechecked and ok)

    Throttle body as been cleaned and cleaned again

    When I had the car back following the head rebuild it idled at 1100 and was fairly smooth (but it was not whining, my interpretation of the engine sound). I had a good go at cleaning the EGR and the revs dropped to 600 but was lumpy. I took it for a run and it started missing ‘code showed up as intermittent misfire on cylinder 2’ (mobile tech) this as not showed up since although it as not been on a run only revving and the short journey back from the garage.

    So you can understand why I need your assistance because the garage have been on to the Vauxhall helpline and they cannot suggest anything except change this then that etc

    My thoughts are that I need to change the MAF sensor to at least eliminate it but after paying so much out I am reluctant on a guess.

    Therefore over to you guys

    My engine still runs (though quite rough) at idle with the maf unplugged, so not sure it would cause the engine to cut out.
    Was the egr programmed/mapped out of the ecu when blanked?

    Chris, yes it is!

    I was reading the web site of that well known 'ebay reader' and on one of the guides/how to, it says that my engine (z18xe) needs the throttle body resetting after work or cleaning to allow it to relearn - how true is this?

    first thing get some carb/ electric contact cleaner give the MAF a clean and let it dry out, see where you go from there?

    has the throttle body been cleaned?
    does anybody no if these cars have and idle control valve?


    try disconnecting the exhaust down pipe and see if that has any help?

    my thinking behind exhaust removal is if there is a blockage in the exhaust this will slow the exhaust gases escaping thus reducing the cars scavenging ie getting lots of clean air into the cylinder. just an idea.

    where about are you to see if someone local could swap MAFs and see if the problem still there.

    Was the T/B cleaned under the butterfly valve?
    Now I need a turbo to keep up!

    i'm in Walsall, west midlands

    There is plenty of blow from it's tail - but it's worth trying if only to eliminate, good call.

    It's making a few people think hard because they do not understand? Vauhxhall help techs sent a t/b test proceedure through to the garage but to be honest, I think I need a degree in vauxhall electronics to follow it

    Yes Big Sig it was

    Just another one. Im pretty sure it won't be, but sometimes when cars fail to idle correctly. Can be down to a faulty temp sensor.

    Like I say I doubt itl be this. As from what you've said it suggests air flow problem.
    But worth bearing in mind if struggling.
    Check wiring and plug connection.

    new thermostat fitted (although not the sensor) temp guage acts as it should shows between 80 and 85 when running and when it goes over 90 when stopped fan comes on and temp drops.

    Please keep them coming because sooner or later there will be something that has not been tried!
