Do I REALLY need a new MAF ?
After digesting all the posts in this forum about MAF, poor performance and iddle fluctuation, Lambad sensor, throttle body , spark plugs etc, I finally decided to book the car for a diagnosis at an Alfa dealer.
Before that, I tried the obviouy that was recommended in this forum, ie: unplugging the MAF connector and it caused the engine to die. My first conclusion was that it wasn't therefore the MAF as the only I could expected from unplugging the MAF connector was an improvement.
The car is now back from the dealer and they told me that the "diagnoser" identified a faulty MAF. They also told me that they replace it ith a new MAF and it runned OK.
Now, the reason why I still have some doubts (apart from the legendary capabilities of the Alfa garages) is that I read in this forum that the "diagnoser" CANNOT reveal a faulty MAF.
Secondly with the invoice for the diagnosis they was no results attached but only the following word on the invoice "...was told to report a faulty MAF" .... sounds abit dodgy to me !
Now, here is a summary of the symptoms and some background info about the car:
1) 156 1.8TS sport pack 1 1998 R-reg, angel tuning remap, BMC Airfilter and 102k
2) car seems to be short of breath below 3k and not pulling away in 1st and 2nd gear. Passed 3k, power rushes in
3) Iddle fluctuates between 500 and 1500 rpm. Problems seems to be worth when warm
Any suggestions before I take the Alfa dealr word for granted and go ahead to buy a new MAF ???
At this stage, any comment will help !!!!
