Hi All,
Here's one to test you, or then again, knowing the level of expert knowledge out there, it could be quite straight forward.
Alfa 156, 1.8 T-Spark runs fine, but at about 3,000 rpm in 2nd and 3rd gear it hesitates or perhaps i should describe it is "pulling back" but only briefly. It almost feels asthough the ignition system is retarding itself if you understand where i'm coming from. The car itself accelerates through this fine, but it is becoming annoying. I'm told by "er in doors" that i'm too fussy and should be thankful that it runs at all !!
Any ideas ?

HI could be the start of the Lambda going down the same symptons could also be Airflow but seeing that it,s about 3.000 rpm more likely a Lambda problem just starting!

Hey GG, this is the tuning and upgrades. Try asking the question in the 147,156 etc forum, am sure you will get a better response.
