    Default Please help :(

    Hi

    I have been a reader for a long time not posted very much. I have a 04 LS, I have owned for a while, I am getting to a point now where I feel like the car is a absolute money pit and I am just thinking of getting rid of it. I have had a incident with it yestarday the check engine light has been coming on over the last week or so ( the yellow one in the bottom right corner) but after the car gets switched off and started up again a few times it goes off (intermittent??) I was driving down the A19 and it lost lost power, the engine was still running and it sounded very low like a bass drum noise. I took my foot off the accelerator and tried to accelerate and found out no power, after a few seconds of no accelerator I tried it again and there was power the engine light was off until this point and it came on. the car was running fine after that. I went out again today and it did it again when I was pulling out my street and then seem to have corrected itself?? There is a hesitation(little dip in power) at about 3200 rpm but other than that it pulls fine through the rev range. I have noticed as well that the idle is a bit lumpy and if I touch the accelerator this goes away. I don't know if my gut feeling of possibly a mass airflow sensor might be right?? Anybody experience similar problems?

    Any advice would be greatly appreciated please

    Thanks

    What engine/miles? It is going in and out limp home mode. You need to get the fault codes read. If I was closer I could have done that for you

    Thanks for your reply, it 2004 1.8 LS, its got 97k on the clock, had full service 2 weeks ago. It just did it for a few seconds and went back to "normal" like nothing had happening just the lumpy idle and light still on. Based on this I think (which is dangerous lol) it might be something like a MAF sensor maybe?? or possibly lambda?

    An old favourite if you suspect a sensor has failed, is to unplug that sensor and see if it makes any difference.

    Most common fault on the early 1.8's is the coil pack breaking down starts with an intermitant loss of power then turns into a misfire.

    As said you need to get the codes read to verify !!!

    Back in a V6 !!!!!!!!!!!! And lovin it !!!

    Just a update for everyone, I bought a new coil pack and fitted it, was only about £45 online, thought it was sorted but happened again, took it to the garage and they got a code reader, cylinder 1,2 and 4 misfire they said it might have been the old coil pack that has damaged the spark plugs?? can this happen?

    Was it a genuine coil pack after market ones can be dodgy

    Hmm
    Usually the other way around, damage to coil pack when removing refitting, or incorrect plugs fitted non resistor type.

    Woops petrol question.......

    Back to the oil burners
