I changed my rear wheels today to the stock 16" alloys on my Vx-S. I then took off to get my 2 19" rims fixed and 1st gear was fine.. 2nd fine.. and then traveled about 50 metres in 3rd gear and my car shutters and feels like traction control sets in and the "low trac" light starts flashing on my dash.. the road was dry and it was a flat part of the road.. this happened several times traveling around the block but only when i reach certain revs/speed in 3rd.. anyone know what the problem is??

cheers
