Peugeot 307 SW 2.0 16v

Anyone help ?

My Peugeot has now twice revved very strongly when changing from 1st
gear (the engines sounds like it is been driven by a boy racer). The
car becomes unoperable and I have had to switch the engine off to gain
control again. It leaves a very strong engine smell. After sitting for
a few minutes it is fine on start up. I have read about flywheel
problems on 307’s, but don’t have a clue what the flywheel is ?

 

I don't know much about the revving problem but I can tell you what a
fly wheel is. It is the huge cog at the back end of the engine that
turns the smaller cogs in the gear box. It is the main driving cog
that moves everything through to your driving wheels.
As for the revving, I have a 99 Ford Ka that has a similar problem to
your car (not as extreme) and the problem is a faulty throttle control
sensor in the oxygen inlet manifold (comes after the air filter).
Don't know if your car has this...I assume it does.

First of all I would forget about it being the flywheel - the only
ones that tend to give any bother are the dual mass ones which are
only fitted to the diesel engines as far as I know - at least on Fords
anyway - it is not a big cog and it doesn't`turn the smaller cogs in
the gearbox !
If it is like Fords I would think it would be the fly by wire throttle
body giving the bother - we have a problem with poor connections on
them sometimes - if you can get at the multi plug try disconnecting it
and reconnecting it to see if this helps - if not you may be looking
at a diagnostic check !
