Dear friends,
I have changed the fuel filter, as this caused a problem previously, but now when I accelerate it sometimes decelerates, if I take my foot off the accellerator then it goes again. Previously some one said that it was a faulty pedal, they have sensors on them so I beleive, could this be the problem? anybosy had the same problem?

Any assistance would be greatful.

What model of Doblo do you have.

It is a 2003 jtdelx 1.9, any help would be greatful, also been having comp problems but a new laptop has sorted that one.

Many thanks

I havent looked at how it works but assuming its a variable resistor (potentiometer) in the pedal somewhere, it could be playing up with dirty tracks, first thing i would try is a good squirt of contact cleaner/wd40.
