muttley 0 Posted November 27, 2009 Report Share Posted November 27, 2009 I had a mechanic friend of mine look at the VR6 yesterday and he said what its doing is called hunting, its where the power dissapears and then the car jolts. it does it in 1st 2nd and 3rd gears. and on tick over it either sticks on 500 revs or the rev will go up and down as if i'm revving the car. im off to town today to get some carb cleaner. i've been told to clean out the air flow sensor, idle control valve and ive got to change a pipe on the fuel actuator valve coz it has a sillicone pipe on and apparently that is very very dangerous coz it can swell and cause a engine fire. I'm also gonna check the plugs and leads.If anyone has any other ideas please let me knowCheersJohn Link to post Share on other sites
VR6Nat 9 Posted November 27, 2009 Report Share Posted November 27, 2009 think you've got most of the ideas.. i would say it would more than likely be plugs, leads or your ISV (idle stabilisation valve). If you check all those i would imagine one of them will sort it... if not let us know! Link to post Share on other sites

muttley 0 Posted November 27, 2009 Author Report Share Posted November 27, 2009 quick update tried to take the plugs out today, two are stuck fast, and two were in a bad way and two were covered in wet oil. also two of the HT leads fell to pieces in my hand.so after one week of ownership the vento is now off the road Link to post Share on other sites

muttley 0 Posted November 29, 2009 Author Report Share Posted November 29, 2009 still got one plug stuck in, it seems to be at a different angle that the rest of them i'm not sure if the socket is going far enough over for it to bite on the nut Link to post Share on other sites
muttley 0 Posted December 1, 2009 Author Report Share Posted December 1, 2009 Ok quick update, i got the git of a plug out and all new plugs are in place, i'm buying new leads tomorrow so that bit is done.i took the MAF out and cleaned it today and the tube running up to the throttle body was cleaned also.I noticed that the throttle body flappy plate ( sorry i dont know the technical term lol) is a bit dirty, can i clean this while it is still attached to the engine or do i have to remove it, i'm a bit concerned coz i've heard that the ecu needs resetting if i mess about with it.any idea's guyscheersJohn Link to post Share on other sites
