    Idle surging

    Hi there, I checked out the alternator last weekend, it did seem to be out putting the correct voltage, but that was when it was just sitting and idling. I've not been able to test it when any surging has been happening though. So tomorrow I'll test it again on a drive and see if the live OBD...

    Idle surging

    Yeah thankfully that car cutting off thing has only happened once! I'll check over the voltage monitoring when I can get the surging issue happening again. Generally happens after the cars been sat around for a couple of days and until it warms up (and I can pull over and restart) it'll keep...

    Idle surging

    Interesting you mention the alternator, it had crossed my mind as I've had some funky electrical things happen - for example when the car is warmed up if I pull over and restart it the idle issue goes away. This has only happened once, but driving along suddenly the engine cut out completely -...

    Idle surging

    No, I don't think there's any cutting out when the engine does surge, the car has just over 70k on it so not a massive number compared to some! I ran through some different apps and found an old archived/inactive 'trouble code' & and ECU Engine manufacturer fault, but after checking a 2nd time...

    Thanks, I'll take another look today and see what I can find. The car doesn't have a tune on it now. When the idle issue first showed up I was having the misfiring issues and needed a good few parts replacing. It all settled down after that for a while so we had a tune booked in. A few days...

    Yep, the MAF sensor was replaced, new air filter etc as in the previous posts so all either new parts or cleaned. I did have a vacuum leak test done which found nothing, when the idle is behaving normally it looks rock solid, the surge isn't like a wobble where it's constant, just a surge...

    Ok great thanks I’ll take a look at them and see if anything shows up

    Ok will check it out, thanks. What scan app have you used for finding the 3 code categories? I'm using an iPhone

    Idle surging

    I believe my scan tool can read pending codes - all the previous codes I've fixed haven't triggered a check engine light at all. I've got a scanner coming today that will read the live data so I'm hoping that'll be more in depth to what I've currently got.

    Yeah next up will be checking the live data, hopefully I'll get time at the weekend but so far it's not thrown any codes at all since the misfiring issue was fixed with a new coil pack, plugs etc. I've had it tested for a vacuum leak too which was my first guess... no apparent issue there...

    Idle surging

    So my issue has been a little bit of an ongoing one for a while and so far I've replaced the below list of parts due to various codes and misfiring issues etc when I first got the car along with general maintenance. Its all stock so nothing questionable done to it as far as I know! Its a 2007...
