Recently My 164S has been acting funny,

1.) The car is starting to sound like a scooter when idle at the exaughst.
2.) There is a noticable decrease in power.
3.) While driving it sounds like a tractor!!!!

This happed last week but after a long trip to the shop it seemed to dissapear. Mechanic said it was due to electronics.

The temperatures here in CT have been Sub-Sero for quite a while.

All i have been able to find was this article....
http://www.digest.net/alfa/FAQ/164/b049501.htm

Im guessing that the problem can be isolated to the intake? :confused:

Does anybody have any ideas or similar problems?

Thankx for all the help,
Massimo

Has your car thrown a C.E.L. when it happend? If it has you could always plug it into a OBD Scanner to see what kind of code its throwing.

Does it sound like theres any vacuum leaks in the engine bay?



To me, It does sound like a ECU problem, try resetting the computer. If not, could be even as small as an exhaust leak or a cracked exhaust manafold.
