Alfa 159, 2.2JTS uneven/high rev idling
I would like some idea why my 2.2jts decides to idle unevenly at around 1250rpm instead of the usual 750rpm. There are no other symptoms. When i startup it idles in the usual range. As soon as its warmed up i see the needle shoot up to 1250. It wont go down from there at all once its up there. For info sake: temperature (climate) has dropped due to winter kicking in here in south Africa.
Please help me before i go on a wild goose chase trying to find out what could be the cause and wasting a whole lot of time and money in the process. Much appreciated! Thank you in advance.
