Any advice greatly received. matiz stalling intermittently whilst in low revs/idle and the power is not there when restarts. After revving up it seems to clear itself. I can be driving along and feel a sudden jerk and kangarooing a bit and I know I am about to stall. Been in garage 3 times. twice, the computer couldnt find a fault. 3rd time, they said I had petrol leak and replaced tank - £300. problem solved for 1 month, now happening again. I dont feel safe driving it at moment. Many threads mentioned distributor, but apparently my model doesnt have one!! Help please!!
