Component Abbreviations
 

:confused: I would greatly appreciate descriptions of the abbreviations used with respect to diagnosing problems with the 944. [mine is a 1983].
Here are the ones I have seen referred to, but there may be some more:
AAV
AFM
DME
ECU
FPR
ICV
ISV
PITA
I realize this could take some time. Is there a list already compiled anywhere?:o

AFM is Air/Fuel mixture or Air Flow Meter depending on context.
ECU is the Electronic Control Unit
and PITA is Pain in the As*
