Goldie 2 Posted June 21, 2014 No the pst i was expecting to make but… There was an unusual noise when i went to start it, it will turn over and fire but dies shortly after. If i feather the throttle i can keep it going but as soon as i stop so does it. Tried an alternate coil pack, same.. Any other ideas? Quote Share this post Link to post Share on other sites
Jon_vr6 1 Posted June 21, 2014 MAF? Have you got access to vag-com Quote Share this post Link to post Share on other sites
Goldie 2 Posted June 21, 2014 I havent mate, i wish i did though… Ive got a spare ISV i can try but no MAF.. Quote Share this post Link to post Share on other sites
seanl82 23 Posted June 21, 2014 Vac leak I reckon, check all your inlet and associated pipework for splits as a first step. Quote Share this post Link to post Share on other sites
mic_VR 3 Posted June 21, 2014 When you feather the throttle to keep it running is it running ok or running rough? Quote Share this post Link to post Share on other sites
Goldie 2 Posted June 21, 2014 Rough as a badgers.. Just changed the ISV, much the same.. Quote Share this post Link to post Share on other sites
mic_VR 3 Posted June 21, 2014 Yep sounds like a vac leak. Is the damper box ok? They tend to crack underneath and around the inlet/outlets Quote Share this post Link to post Share on other sites
easypops 8 Posted June 21, 2014 I have a spare maf mate,plus one on the car, how many pins is yours? Mine is 4 pin. Only asking as I've seen a VR6 with different pins, 5 I think? If yours is 4 you are welcome to try them out :) Quote Share this post Link to post Share on other sites
Goldie 2 Posted June 21, 2014 I may need to take you up on that Martin.. Tried another damper.. Can hold an idle but sounds terrible.. My MAF is the one with the silver panel on it.. Quote Share this post Link to post Share on other sites
easypops 8 Posted June 21, 2014 Mine has no silver panel? It does have a K&N filter sticker lol, so silver panel might be under that? Part number of the spare is 021 906 462, it's a BOSCH and it looks just like the one on the car Quote Share this post Link to post Share on other sites
Jon_vr6 1 Posted June 21, 2014 Try unplugging the maf and see if it makes it run Quote Share this post Link to post Share on other sites
Goldie 2 Posted June 21, 2014 Update.. Changed damper box, can get it to run, sounds like a 3 cylinder.. Pulled each HT lead one by one and they appear ok. Disonnect the MAF while running and it starts to stall, reconnect and it starts to run a bit better. Bit stuck now, was getting up at 5 to head to a show, looks like that is sacked..

easypops 8 Posted June 21, 2014 If you want to try these MAF's, I'm in all night, and planning to watch the football, so not going to sleep anytime soon Quote Share this post Link to post Share on other sites
Goldie 2 Posted June 21, 2014 Would a MAF affect the start up? Quote Share this post Link to post Share on other sites
easypops 8 Posted June 21, 2014 Also, I'm sure I've read that the sponge in the damper box can break up and get sucked into the pipes? Might be worth taking them off to check they are clear Quote Share this post Link to post Share on other sites
Goldie 2 Posted June 21, 2014 The sponge was hanging out the damper when i took it off.. Quote Share this post Link to post Share on other sites
easypops 8 Posted June 21, 2014 Would a MAF affect the start up? Not sure mate, I'm not that knowledgable , hopefully someone else will know? I've probably got a spare ISV and damper box too Quote Share this post Link to post Share on other sites
mic_VR 3 Posted June 21, 2014 (edited) Make sure none of that sponge has been sucked into the inlet tract Edit - I see that's already been suggested Edited June 21, 2014 by mic_VR Quote Share this post Link to post Share on other sites
Jon_vr6 1 Posted June 21, 2014 If theres a notable change in engine note when you unplug the maf then id say the maf is working properly Quote Share this post Link to post Share on other sites
Goldie 2 Posted June 21, 2014 Id probably agree Jon.. I can get it to run but it 'put puts' and doesn't sound great. I don't want to do much more tonight,the neighbours won't be impressed with me starting and running the car.. Do you have Vagcom Martin? Quote Share this post Link to post Share on other sites
easypops 8 Posted June 21, 2014 Just the free one mate, I also have a code reader that I've yet to try,not sure how much the free one tells you as I've only used it a couple of times Quote Share this post Link to post Share on other sites
Goldie 2 Posted June 21, 2014 Better than nothing.. PM inbound... Quote Share this post Link to post Share on other sites
Goldie 2 Posted June 21, 2014 Another thing worth adding, if i disconnect the ISV plug with the car running it makes no difference.. Quote Share this post Link to post Share on other sites
Jon_vr6 1 Posted June 21, 2014 How old are your ht leads the gf had a weird stutter and sounded rough on idle and driving. Turned out to be 1 dead ht lead and was running on 5 Quote Share this post Link to post Share on other sites
Goldie 2 Posted June 21, 2014 I pulled them one by one and each one affected the running so assume them to be ok.. I can't help but feel the noice when i first started it was significant. It was a thud/crack noise, I've no idea what though.. Quote Share this post Link to post Share on other sites
