GSR2007 Posted June 21, 2016 Share Posted June 21, 2016 Hi guys having some issues with my 95 tt the car was running fine for the first few days of bringing it out of the shed for the summer, but now the car does idle lumpy and for some reason my bov is hissing alot more with little or no boost pressure? Also coming on second turbo the car some times hesitates/holds back I have noticed an obvious blow in my exhaust where first decat meets the cat could this be the root of my issues? I've checked all vaccums and boost pipes and they seem fine also done pin test as light flashed after a hard run was error 42 speed sensor any help would be greatly appriciated Quote Link to comment Share on other sites More sharing options...
GSR2007 Posted June 21, 2016 Author Share Posted June 21, 2016 ^^^to clear up above when i say blow off valve hissing litterally the tiniest bit of trottle and lift off it makes its usual noise where as before it took a good but of pressure (hks ssqv4 possible rep) Quote Link to comment Share on other sites More sharing options...
mellonman Posted June 21, 2016 Share Posted June 21, 2016 Maybe the blow is letting you make more boost? what boost preasure are you reading I doubt a slight blow would make much difference though Quote Link to comment Share on other sites More sharing options...

mellonman Posted June 22, 2016 Share Posted June 22, 2016 Well the boost is spot on, hesitation could be down to if you bad fuel from storage, ecu learn if the battery has been disconnected, I would put some nice fresh shell nitro in and drive if for a longish drive and see if you still have issues , other then what I have said coil pack clips are a common place to cause misfires Quote Link to comment Share on other sites More sharing options...
GSR2007 Posted June 23, 2016 Author Share Posted June 23, 2016 Fixed the blow in my exhaust and changed blow off valve didn't solve my problem,so I'm going to change fuel pump and fuel filter,change plugs and coilpack clips and go from there I'm hoping that will solve the problem Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted June 25, 2016 Share Posted June 25, 2016 Are you certain no boost hoses have partly blown off? Look especially at the one down the side of the battery. Give them a REALLY good tug and twist. Check the ones to the IC, you'll have to remove the arch liner / lower cover. Quote Link to comment Share on other sites More sharing options...

Checked intercooler pipes all ok all vacuums seem fine,took it for a drive the other day and it ran great for a long time idled sweet then after a very small bit of spirited driving it started acting up a bit again im just going to drive it casually for the next few weekends them take it off the road and golet my mechanic to go over everything and replace anything that looks in the slightest bit fragile, coilpack clips are ordered now also and looking at small single kits and standalones can't see myself selling so I don't mind spending a bit on it to have it perfect Quote Link to comment Share on other sites More sharing options...
