problem with 156 2.0 JTS


My problems are the lower acceleration and the higher consumption than before.
Two months ago, car accelerated like thunder and consumption was 8-10l. Everything worked great ! But now it doesnt...
When I accelerate, it still goes smoothly as before (almost), but with less power... My 0-100 km/h time is now 3 seconds higher than it was 2 months ago... And consumption is now almost 20l / 100 km !!!

Re: problem with 156 2.0 JTS

Could be all sorts of things, but a well known problem is the life expectancy of the MAF (Mass Air Flow sensor). It can be cleaned, but having a spare one is a good idea so that a known good one can be tried when having performance problems. Do not buy one from the Portand Group. Alternative Autos are supposed to be a good source, wherever you get one from, ensure that it is a genuine Alfa or Bosch part.
