This is not a medical question.....my DB9 appears to me to lurch to the left when accelerating and to the right when I take my foot off the pedal.....how does this happen?? Engine mount problem? The wheel alignment has been done by my AM dealer and they don't appear to agree that there is a problem any longer.....The car has no where near as much torque as my previous car which would run in a straight line regardless.....
Appreciate the assistance...
Rgds, Brin

Not in this case as both the tyre pressures as just digitally checked are as near as makes no difference 2.8 bar...

For purposes of closing this thread; the solution to my car lurching upon acceleration and deceleration was found in the rear tyres. They were same make but different generations of the same brand. Replacing the older tyre to the same generation as the new one solved the problem. Lesson learned, always change tyres in pairs.

Interesting. Who would have thought that would have so much effect.
