2005 E270 cdi Sticking Throttle

[GeoffWestWales]

Hi all,
The last few drives when going down our 1/4 mile farm track the throttle seems to stick at around 1250 rpm, its more noticable from cold, went to the local supermarket so engine fully warmed up and it did the same thing causing a really harsh and jerky down change, I assume this is a fly by wire throttle so may be a position sensor?, it only lasts for approx 300m then is as good as gold, not had a chance to plug my iCarsoft MB v 2.0 in yet as friends are visiting so swimbo has kept me busy, any pointers please?
Thanks in advance
Regards
Geoff

Could be a faulty throttle pedal sensor (all in one one these) or a wiring fault.

Thanks for the reply Alexander, will price up a throttle pedal sensor, fingers crossed it wont make my wallet bleed to much

Do check the wiring first! It's 50/50!
