Post by: dan_thevdub_man on 24 March 2013, 18:51

i knw i have posted this question many a time but im starting to get wrried now...
iv replaced ht leads spark plugs etc and dizzy
air filer replaced and maf cleaned with contact cleaner, i need to clean the throttle body but...
regardless of this when i start the car on cold i will not idle and if it does it hovers around 800rpm then dies, i have to keep throttle down for about 3 mins at bout 1000rpm then usually it idles perfect at around 650-800rpm. is this common and what are the usual fixes..or could this be something more sinister. iv seen someone mentioning ecu and various differant relays
its the 8v 97 agg

Yeah a doddle.They plug in the fuse box which is located under the right hand side of the dash.There should be a cover over the fuse box with 2 green clips either side of the cover.Pull that cover off and you should see the fuse box.Either side of the fuse box are 2 white clips that push up allowing you to drop the fuse box out.Sounds difficult but it aint m8.

ok cheers mate. before i buy the relays tho is there a check i can do on them to make sure they arent working

Good question.I have read that if they are warm they are working ok but believe me that aint always so.When they get warm the contacts inside can seperate causing allsorts of issues including cutting out,bad idling,etc.I would just change them for peace of mind and they are a cheap enough fix.

Dan,one more thing you can check is the temperature sensor especially if your having problems starting on cold mornings.http://www.golfgtiforum.co.uk/index.php?topic=101400.msg862334#msg862334
