So I was driving down the motorway earlier and all of a sudden the VX started to jerk and clonk as if there was a sudden loss of power and then lots of power quickly. I knocked it into neutral and she revved freely and seemed ok, so put her back into drive and there was a distinct lack of power. If I tried to accellerate hard she would do the jerking thing again. She seemed ok though if I sat at 60 without accelerating, so continued to my destination about 20 miles away.
On the way home the jerking and loss of power seemed to come and go until eventually she died altogether - managed to coast to the side of the road and sat there scratching my head. Checked connections etc under the hood and all seemed ok. If I tried starting her she would start, run roughly if at all and then die. I walked a couple of hundred feet to see which mile marker I was at in order to call the recovery guys, but when I got back she started and idled fine. So I carried on my way, very tentatively. I got about 15 miles before she died again - just after I needed to accelerate, so that obviously starts the failure. After 10 minutes of intermittently trying to start her, she started ok again and I carried on. Got another 10 miles before it happened again.
Finally managed to get home but my VX isn't a happy bunny
So, firstly sorry for the long post, but has anyone got any ideas? My first thought because of the jerking and clonking was maybe the torque converter, but later on she fails to start, so don't think its that.
Did notice if I stuck her in neutral and coasted it seemed as if drive wasn't disengaging, but I could be imagining it! The revs also didn't drop unless you revved her, but then she was ok. When running, idle is ok and not up and down.
Any ideas????
Thanks guys
