Hi Guys
My 2.5L idles like a V8!! ie its not a smooth rhythm but it isnt rocking the car..., but I havent heard another 156 V6 yet to compare it with altho the guy who did the road worthy thought it a bit rough..
The car feels eager to accelerate when driven and is smooth on the road.
After reading Festy's recent posts on the T spark. Which have been fascinating.
Im wondering if my 2002 vehicle has some unknown ailments.
Could members please comment on what the idle of a 2002 V6 is like.
Is a little roughness normal?
thx
I experienced the same thing with my 164. Sounded like it was misfiring and running like it had a big cam in it.
Changed the spark plugs and it was all good after that.

have had platinum plugs in for a few months now..
To answer your question, definitely doesn't sound normal, I have a 2001 156 2.5 and a 2001 GTV 3.0 and neither idles roughly.

Hi Joori
thanks for the offer of help. I lost a couple of hose clamps when working on the engine last year!
2 for the hoses that go into the back of the inlet manifold that sits on the rear cylinder bank. Will fix this up and see if a partial vacuum leak is not the cause. Will keep the 'lumpy idle ' post going, hope to catch up at a club meet (better renew my membership!) cheers
ps how is the search for a GTA going?
I had a similar issue - Lambda sensor seemed to be the cause. Changed it now all is good. Also check for air leaks in inlet hoses.
I've a diagnostic tool I would be happy to plug in for you to see if there are any error codes. I'm in SE Suburbs of Melbourne.
I havent bought one yet. Sortof stopped searching. I invested my alfa money into my "workshop". I want to kit out my garage first, then i will buy a GTA.
