('96 model) but just recently she's started to stall when i fire her up unless i give her a bootful of revs, any ideas why this has just started now?Just moved house & the people next door don't like me revving it to start it. It wakes there kids up! lol!Thanks for any help you can give. ~ Link to post Share on other sites

VRmonster 1 Posted April 1, 2004 Report Share Posted April 1, 2004 idle start valve i beleive. not sure where its located. need more tech info lol. Link to post Share on other sites
jamieVR6 0 Posted April 1, 2004 Author Report Share Posted April 1, 2004 Ahhhhhh! sorry mate now i understand lol, thats why she sometimes hunts for revs when i'm sat at traffic lights. How do i fix this? Link to post Share on other sites
mightyvr6 0 Posted April 1, 2004 Report Share Posted April 1, 2004 stabiliser is correct. Its at the back of the engine bay right hand side of the TB, hidden under black plastic. Link to post Share on other sites
VRmonster 1 Posted April 1, 2004 Report Share Posted April 1, 2004 under the one with the stardrive bolt? cos i been wanting to check mine. my revs fluctuate badly for about 5 mins after starting. can you clean them? Link to post Share on other sites
mightyvr6 0 Posted April 1, 2004 Report Share Posted April 1, 2004 yes under the rear plastic cover. Give them a good spray with carb/injector cleaner. Link to post Share on other sites

vrPat 0 Posted April 1, 2004 Report Share Posted April 1, 2004 I've got a similar problem on mine - it just needs a blip of the throttle to start, only when the engine is warm. Its more apparent in the warm weather and sometimes stalls when pulling up.On VAG-Com it says:00533 - Idle Speed Regulation 14-00 - Adaptation Limit (Add) ExceededReadiness: N/ADoes anyone think that cleaning my isv might cure the problem?sorry if I'm being thick here Link to post Share on other sites
jcorallo 0 Posted April 1, 2004 Report Share Posted April 1, 2004 00533 - Idle Speed Regulation14-00 - Adaptation Limit (Add) Exceeded===============================@vrpat - Go back to your VAG-COM and find what value the idle adaptation measurement block has. Go through the measurement blocks till you get to the one that shows "Idle Adaptation" and "Part Throttle Adaptation".The idle code should be at or near 1.0So if its greater than 1.0, the ECU is adding fuel to try and counteract a lean condition. This can be an air leak in the intake, or even near the Lambda probe at the cat. If the cat gasket is blown for example, you'll see this code approx +1.5If its less than one, the ECU is trying to hold the fueling back - which means you have a rich condition. This can be caused by a leaky injector or too high fuel pressure.Like I say - go see the value in VAG-COM and act accordingly. Once you know the value - go a hunting!Jules[ Edited Thu Apr 01 2004, 11:27PM ][ Edited Thu Apr 01 2004, 11:28PM ] Link to post Share on other sites
mightyvr6 0 Posted April 1, 2004 Report Share Posted April 1, 2004 might be knackered but check hoses for splits and clean it out firstly. clear codes and reset the ecu then go out for a drive and recheck using vag-com. make sure throttle angle doesn't exceed 14 degrees.

VRmonster 1 Posted April 1, 2004 Report Share Posted April 1, 2004 this is getting too technical for me. lol. i think its time for me to get myself a vag-com Link to post Share on other sites
vrPat 0 Posted April 1, 2004 Report Share Posted April 1, 2004 wow cheers for the quick advices chaps you're stars! I shall have a look tomorrow at the value and report back. Link to post Share on other sites

28v6r 0 Posted April 2, 2004 Report Share Posted April 2, 2004 No danger there then:-)Once SPOTLESS, working the door etc, lubricate the door with some 3in1 oil and reinstall. Now moving further along, look at the throttle body, it's held on by 4 10mm bolts. Remove the throttle body and clean the butterfly until spotless and again lubricate. Now there's a thin paper gasket between the flanges, it's 40p so replace that as well, When reassembled don't panic if the revs are erratic, it takes a little time for the ECU to reset to the "Alledgedly" new valve, It will settle, and your throttle response will be crisper. Try that and see how you go, you may find that because of all the gunge in there that the Throttle switch (Black plastic part on the throttle body may need reset, this also has to do with the "Stalling "part of things) but see how you get in....Good Luck, and remember we're never that far away....:-)Regards28v6r Link to post Share on other sites
vrPat 0 Posted April 4, 2004 Report Share Posted April 4, 2004 Hi again - sorry to be a pain, but is this the correct location for the ISV? Could someone circle the ISV for me? I've obtained some carb cleaner and will give it a good clean when I've worked out exactly which part needs to come off!Jules: Again many thanks for the help, I have been through the engine/measuring block section of VagCom but I can't find the "Idle Adaptation" or "Part Throttle Adaptation" value? sorry if I sound like a thicko - its not that I'm not mechanically minded, just I'd hate to get it wrong and break anything Link to post Share on other sites
jcorallo 0 Posted April 4, 2004 Report Share Posted April 4, 2004 @vrpat - um - scrub what I said - fundamental mistake - I didnt ask if you were OBD1 or OBD2! !dodge You are OBD2 so the VAG-COM info will be different. What I said above still holds true generally, but the info you get will be different I think. OBD2 gives you a LOT more details about how the engine is running but I cant help you in this respect.I suggest having a search through (or pop a post up) on the VAG-COM group on Yahoo.....!
