If you remember the film Chistine then I think my 406 has the same condition. The car has mind of its own. Cruesing at 50-60 then the car suddenly takes off by its self up to 5000rpm on the rev counter. Also when at traffic lights the car lurches forward and it take a lot of brake power to slow and stall the engine.
Which engine? DaveK
My 406 does this, it's a 2.1TD LX estate...
Any Ideas.

Sticky throttle, have you checked/replaced the cable?
Exorcism?
Took the "Christine" to the Puegeot main dealer for a diagnostic check up, and in1 hour the verdict was a faulty "Stepper motor", what ever that is, cost £28.. Parts quotted at £85 and £57 labour. I said thanks but no thank you, went to Halfords bought a Hayes workshop manual and stripped the part (easy) . The Stepper motor was seized so I took it apart cleaned and oiled and reasembled. It took 1/2 hour to do, and now "Christine" is now as gentle as a pussy cat. Brian
"Sometimes it works temporarily to strip and clean the motor"
Apparently the problem is caused by wear on a plastic 'shim' piece in the stepper motor causing it to seize and give erratic idle.
It turned out to be a stepper motor problem....cost £37 to strip and clean Brian
