    idle problem fix

    i have been looking for what has been causing my idle problem , revs drop and come back up and only dose this on idle when i pull up at lights. i have tryed every thing to sort this problem

    like cleaned throttle body and reset with vagcom
    also cleaned injectors
    changed plugs
    change coil packs x4
    air filter
    fuel filter
    lambda sensor 1 as i had vagcom fault code
    and changed egt sensor as i had fault code.

    all codes gone and not come back

    and i found how to get the idle to stable all the time all i done is unpluged the egt sensor and took it for a drive for a few days and its fine all the time , but what damage will it do if i leave it unpluged
    will the car overfuel

    Check the vac hoses underneath the inlet manifold, mine had the same problem and this was the cause.

    cant be good driving around with the EGT unplugged. I am pretty sure will overfuel and you will loose power too. Your not considering driving it from now on with the EGT unplugged are you? Does the EML light not come on with the EGT unplugged?

    I going to take a wild stab here as it sounds like you've already looked at the easy things.

    It sounds like especially with the poppin, that you have a leak in the inlet gasket or injector bungs. Drawing in etc air and causing the idle problems at misfires.

    Easy way to check and I used to use this on Dellorto carbs, is to spray WD40 around the inlet and injectors, covering well the area. If the problem goes away you have a leak from either the inlet gasket or injector bung, which are common to go.

    Worth a try.

    Is that the plastic seat in the inlet manifold the injector seals sit in? Have you got part numbers and prices?
