Hi Groovygal no acronym list here yet, but it would be listed as AAL.......................Automotive Acronym List, I think:pinch:
True there are a Zillion of the critters! Try either an online search for such a list, OR public library might have Mitchell manuals in Reference Section. Look for Mitchell or any manual that covers Emission Control Systems, that's where so many acronyms oriiginate. If you look at beginning of Emissions controls section in many car manuals you'll find list of these dandies.
PCV: Positive Crankcase Ventilation
EGR: Exhaust Gas Recirculation
IAC: Idle Air Control valve
Some car computer acronyms:
PCM: Powertrain Control Module
