I own Punto 55S, y. 94.

Some time ago my car started to turning him self off. I went to authorized service, and they have cleened my electronic injector. after that (in driving) my car starts to lose pover on moments (like pulseing) - been to service and they cleaned injection system. After some time it started all over again - i don't know what to to, what seems to be the problem.
Please help

tnx in advance

P.S. sorry 4 english

i think u might hav to check your sensors EGR valve and the lamba sensor if there fine then sounds like your coil pack is on its way out. they are around £50 quite common on the 55 puntos. u will no straight away if its that if the car vibrates really badly cause it will only be runnin on 2 or 3 cylinders.

EGR on a 55! you sure?
More than likely to be the Lambda probe or the coils.
