1997 MPi
Mi Mpi started to judder from time to time when drinving slowly in traffic jam or other slow driving situations.
With full trottle or higher rpm the engine runns nice.
But when i like to drive slowly with just tipping the trottle the car starts to judder.
the difficult thing is this happens not everytime but more and more.
Didnt had that before and changed nothing. Sparkplugs and Fuelfilter are almost new around 1000Miles.
Trottle valve problem maybe? or injection valve?
