2000-3000 flat spot
I just took ownership of a beautiful 1999 156 2.0 TS just 3 days ago. It is my first alfa and absolutely love it.
One nagging concern. On take off, particularly in first and second, between 2000 and 3000 rpm there is a significant lack of power. Over 3000 and its a little rocket!
Now, I am not asking questions without doing my research. However my research on MAF issues, which was my immediate diagnosis, has been challenged by a few posts which describe power delivery issues in the higher ranges where mine seems to be fine. Also, the car seems to have a relatively new MAF (The part number is the new 019 despite the car being a 1999 model)
So, I am thinking one of two things. First I read that if the temp gauge is not working then as an auto safety power will be withheld below 3000rpm. My temp gauge only sits just 5mm above 50. is this right? I have never seen it hit 90.
Secondly, possibly the oxygen or "lambda" sensor before the cat. But does this sound right for a low rev range flat spot?
Lastly, it is not "that" severe and I know different engines have different natures. Is this just a twin spark characteristic?
Thank you all so much in advance for your help.
Looking forward to hearing from you.
