    my car idles like a bag of **** coughs and splutters all over few bullet points first
    *If you put slight gas on to 1.5k revs it doesnt do it
    *when you first start car and rev limit is higher for a min or so it doesnt do it till it starts dropping
    *i have had all new coil packs and maf (cars a 1.8t)
    *i have the wrong lamdba wiring in from conversion which is going to get changed but with the same wiring its idled mint for over a year
    *had a pressure test and car holds good pressure on jakes leak tester
    *had new dv
    *loads of new piping
    *throttle body cleaned and aligned when conversion was done

    I have had other bits and bobs done but will remember if people say it


    What options could cause a really really bad idle really bad

    My car doesn't always idle smoothly either... perhaps not as bad as yours sounds, I always thought it was just the character of engine
