tjsmudger 2 Posted November 3, 2009 Report Share Posted November 3, 2009 my vr6 golf has been running like a bag of spanners, its fine when you start up, becomes almost unresponsive, backfires now and again. shows up on VAGCOM as a idle speed problem, Read on here could have something to do with the MAF so i bought a new one, no change.It is particuraly bad on the motorway when wanting to select a lower gear, the sound is almost a drone, the revs move up but no power. it is at times like driving a car with very bad turbo lag. Going through a rather large amount of petrol lately, when it drones, i get a very strong smell of petrol.HT leads have been changed, coilpack is year old and just had a full service, any answers or suggestions to my dilema would be greatful, as im having to justify to my wife , why i have to spend X amount of money all the time on this blooming car. not my words, the words of my wife!!!!!!

Dave_ciw 507 Posted November 3, 2009 Report Share Posted November 3, 2009 Sounds to me like its missing on one of the pots ......... Plugs, leads then coilpack. You say the leads and pack are new and a service was done so new plugs??????????? Did you buy a new coilpack or second hand?? Link to post Share on other sites

rodney 17 Posted November 3, 2009 Report Share Posted November 3, 2009 The basdics here really..check you throttle body and intake pipes/MAF (done but check connector is clean and fluid free) the spark zones such as coil pack and plugs and cables,THe Lambda is always good for crappy runningthen finally is/are your fuel/filter/injectors ok??let us know how it goes there fella..

Rikki 2 Posted November 3, 2009 Report Share Posted November 3, 2009 I would guess throttle body on obd2 this controls idle! Link to post Share on other sites

AJmk2 2 Posted November 3, 2009 Report Share Posted November 3, 2009 When my coilpack went it definatly didnt sound the same on tickover. Maybe check your lambda sensor if its overfueling like mad. Link to post Share on other sites
