    Help, my mk3 is dying. 1.6 16v eco

    I think an expensive problem is arising. 2 days ago my astra started chugging for a split second at a time, the gaps between it doing this were quite random and didnt really make much difference to the drive.

    as usual it gradually got worse and yesterday i got so bad that the car stalled and wouldnt start without flooring the pedal, even then it seemed to hesitate. i had to rag it home keeping the revs above 3k.

    I started the car this morning and it seemed to idle fine then when i hit the gas the revs dropped almost to the point when it stalled and then picked back up.

    the exhaust pops and splutters when the problem starts.

    the car pulls to 100 but still splutters on the way and loses power now and again.

    i changed the spark plugs earlier and they were covered in oil, burnt yellow and the electrodes were burnt down quite a bit considering theyr only 3 months old.

    after the plugs were changed it ran fine for about 20 miles then it started spluttering again.

    Please help its, really frustrating when you know theres a problem but have no idea what it is.

    EGR Valve gave me similar problem's with regards to the spluttering but it could also be your dissy cap or leads.

    could be anything really...lol

    I checked the leads they all seem ok, not sure about the dissy cap though.

    the management light flicked on for a couple of seconds yesterday after i changed the plugs but the car ran fine for about 20 miles. just read this link

    http://autorepair.about.com/od/gener...l/bldef165.htm

    says that the valve needs back pressure to open it. when i pop the oil cap off there doesn't seem to be much back pressure like there used to be. before when i loosened the cap and left the engine running the pressure would move the cap. this doesn't happen anymore.

    anyway the cars booked in for a check on saturday.

    is a tech 2 where they put it on the computer?

    thanks for the advice

    just started the car up and a cloud of smoke come out of the exhaust. the car sounded like a drag car. really lumpy.

    iv removed the new spark plugs and theyr covered in a thick layer of soot. the pots that they screw into were also smoking a bit when i removed them.

    would the egr valve do that to the plugs in 1 day?

    Mk3 will need a Tech1 I think.

    My first thoughts would be the coilpack breaking down, which is pretty common on that engine.

    good news, the problem was nothing serious.

    The garage ran a check on the comp this morning and discovered a faulty water/air temp sensor aka coolant sensor. The mechanic said that the engine was being starved of fuel.

    They charged me £35.00 for the diagnostics and £20.00 for the part and labour.

    Im happy with that, thought it was gonna be something expensive.
