Woodyman84 3 Posted May 11, 2013 Report Share Posted May 11, 2013 While i was checking out fault codes etc on the VR i noticed that at around 1500rpm the revs hunt up and down, kinda like a little misfire. and when the revs dip there is a fairly harsh vibration.it idles perfectly smooth and above 2k it doesnt seem to be that bad but maybe just less noticibleNo fault codes and i recently replaced MAF with a brand new oneany suggestions welcomeIll also be linking a video shortly (no sound tho sorry)oyWyIfp73rs Link to post Share on other sites
VR6Pete 1,455 Posted May 11, 2013 Report Share Posted May 11, 2013 Did you do a throttle body adaptation after having battery disconnected? Link to post Share on other sites
Woodyman84 3 Posted May 11, 2013 Author Report Share Posted May 11, 2013 Erm most probably not doh. Link to post Share on other sites
Woodyman84 3 Posted May 11, 2013 Author Report Share Posted May 11, 2013 Not sure it is this tho. I'll try it. If not I'm think ht leads or plugs Link to post Share on other sites
VR6Pete 1,455 Posted May 11, 2013 Report Share Posted May 11, 2013 (sorry assuming you are OBD2 here) If you have had disconnected the battery, and didn't allow the throttle to perform it's own adaptation when you put ignition on axillary) then that might not help you can do it on VAG-COM, only takes a minute, so worth a shot, presume you have re-seated your HT leads etc... when were your plugs last changed?

Woodyman84 3 Posted May 12, 2013 Author Report Share Posted May 12, 2013 Had.to do.the.chicken dance as my Fisher price vcds doesn't let me do tb alignment. Took battery off put back on, left in ignition stage for 5 mins, checked there where no fault codes.Does seem to feel alot smoother under load. I'll get someone to do a proper tb alignment at rr day :-) Link to post Share on other sites
VR6Pete 1,455 Posted May 12, 2013 Report Share Posted May 12, 2013 Doing that is practically the same thing anyway but if it feels better all good, does it still hunt? Link to post Share on other sites
