dubber lister 0 Posted October 16, 2010 any help peeps its getting worse everytime i dip the clutch while driving the revs drop and it cuts out. iv had the isv soaking in carb cleaner all day and this made no difference iv also changed all the vac hoses around the airbox.

Mawrick 0 Posted October 17, 2010 Had a similar problem on my Passat VR6 - checked out lots of stuff including cleaning the ISV etc. Turned out it was sucking in "false" air, so might be an idea to have a look around to see if it takes in air it's not supposed to......Mine was a bit better when the engine was warm - but still not good.

dannyboy 0 Posted October 17, 2010 can you smell raw fuel from the exhaust after starting? check all air hoses are attached and havent got holes in them. The idle screw rubber sealing ring does perish over time so might be worth replacing. Check condition of dizzy cap and rotor arm,check ht leads it could very well be the fifth injector.since you unplugging it made no change shows you its not working!check the wiring and do a ohms check on the wiring. then check injector itself. had same prob with my mk2 gti turned out to be a loose fifth injector wiring and high resistance(corroded).
