V8 vantage throttle sick but not throttle body

[michael-o1z5e]

Would appreciate any input. The vantage has developed a problem, I've cleaned the throttle body but with no avail. The problem persists, the higher the revs the more likely it is to start self revving in and out of gear.

Any advice or diagnosis ? I'm south east kent so nearest garage is 1 1/2 drive

Yes idle is steady, sorry I should have made more sense, after driving and revs reach over 3000 the car starts lunging forward, so I'll take it out of gear and coast, the revs then fluctuate before maybe revving up to around 4500-6000.

Since last posting I've not had the time to send in to AM, I have however taken it around the block to see if it was drivable to reach Sevenoaks, and issues as follows.

It's not over self revving at all now, it drives like it use to all but. I've had a few lights come up as follows

Traction control
ABS
Hand brake
Red triangle warning

Traction control temporary off
ABS / DSC service required
Emergency brake assist failure

Has this happened to you / especially krisdelta ?

Will it be ok to drive hour or so to drop in and what's your recommendations ?

Thanks, yes it's a manual. The lights arnt on all the time they've only come on twice but when on ot doesn't over rev.

I've changed the abs/ speed sensors, I assumed it wouldn't need resetting each time as I only brought one and frog leaped them to the next each te I test drove it, still no avail.

I'm guessing the speed sensors pick up spaced magnets in the hub which give the reading, do these magnets deteriorate or become un-aligned ? * above especially did aston Martin tell you what happened to your hub when they replaced it ?

I did have a little bump on a curb maybe 7-8 months ago and had to change the alloy, do you think that may have something to do with the problem.
