Vito reving it's n**s off! help

Hi all
When I push down the accelarater,and release, sometimes it keeps going up in the Rev's until I have to switch off and start again.

Anyone with advice (apart from the Merc dealers- CC maxed out!)

I have no idea if this is relevant but I used to have a VW with a dodgy throttle return spring. If I accelerated gently it was fine, foot to the floor and it would just jam open. Could be quite interesting at times.

I had a similar problem with my old VW Transporter. Turned out to be an age thing and just needed a lil bit of lubrication around the moving parts
Never underestimate the force that is....... WD40! You just never know it could be all it needs (hopefully)

Spring has sprung so off to the spring shop it is!

The throttle in these are like fly by wire.
When you accelerate the cable actuates a magic box which sits up under the windscreen behind the heaterbox air intake ductwork, passengers side, engine compartment... (On a RH drive, don't know where it is on LHD). On my van 108CDi, the after market A/C pipework as fitted by the MERCDAD pushed the bowden cable to the point that it was around 30 degrees off straight...
Rerouted the cable to the other side of the pipework & now it is straight & as smooth as, accelerator pedal that is. Maybe your cable is frayed, you'll be able to see what happens when you find the end of it.
There should be 2 springs on the mechanism. 1 strung between a fixed point & the arm. The 2nd one is around the centre shaft of the actuator. (This is the thing that also stops your engine going back to idle immediately you take your foot off the gas. Those who have a dead speedo will notice this no longer works & you have to change the way you use the clutch. I digress.)

If yours has the cable run properly then check other mechanicals in that area & unplug the unit & replug it, sometimes swiping the terminals is enough to cleanup a dodgy connection. Sometimes. After the basics it gets expensive.

Cheers, Matt.
