01 MK2 VTS - Still in LIMP mode ? :/

  1. #1
    Guys, I was in a drive through just below the red.
    The car dropped to what sounded like 3 cylinders. loud tractor sort of sound, real slow pull away etc, etc

    Topped up on fuel, half way home it was still on 3, then kicked in on all 4 and was running sweet, then just before I go to my road it went down to 3 again.

    I replaced,

    Fuel Filter,
    I have stripped the injectors, cleaned them all, around the head, fuel rail etc etc.

    Started it, and it sounded sweet, Just drove about a 15 min journey on the way back it dropped to 3 again...

    Any advice would be great guys

    Oh, and I used some fuel treatment also

    No I didnt change the plugs, I replaced them just over a month ago they are NGK's aswell.

    When I took them out and inspected them, they all look a bit sootie, So i popped them in the vice and cleaned them all, placed back in again.

    Defo sounds coil pack related tbh but I'm guessing that's been changed? And Is it plugged into the wiring loom ok?

    It's probably just a co-incidence tbh mate, I'd of thought it would of been an injector clogging up from the shit in the bottom of the tank, but if it's an injector or spark plug then they normally boot up and work as the revs go higher, and coilpacks just work when they want lol when they start to pack up

    Well it will be while I am driving, and it will clear after I push hard to high revs, then it comes on all 4 again and away I shoot... Still CP you reckon?

    As I say as well, I have dripped all my injectors, cleaned them all, and around the inlet, and rebuilt

    It worked Ok, straight from the rebuild, went for abit 15 min drive, and its back again... I have used Fuel treatment, and changed my filter but still the same.. So I am going to try coil pack, and also get some new plugs even though they are 1 month old

    What condition is your lambda sensor in IE a sooty colour on the probe?You`re overfueling thats why the plugs are a sooty colour(coil pack can cause this)

    Tested - Seems to be ok, took it for a good rag and it seems to be ok for the mean time! I will confirm if in the future same fault applies!
