Help for New users on abbrev

I have noticed to constant of three letter codes for parts and devices.
Have figured out most of them such as:

o2s = Oxygen Sensor
ECM or ECU = Electronic Control Module
CEL = Check Engine Light
KER = Keyless Entry Remote

Well, you if know any other abbrs that would be helpful - please post here.
Thanks

Oh, By the way,
what does FOB stand for other than Fu**ing Outside Button.

Some common ones around here..

IMG = intake manifold gasket
IAC = idle air control valve
VSV = vacuum solenoid valve
FSU = fuel sending unit (not f**k s**t up, thats a whole other forum)
EGR = exhaust gas recirculation
PCV = positive crankcase ventilation (not PVC which is poly vinyl chloride)
SOTF = shift on the fly
SRS = suplimental restraint system (air bags)
FPR = fuel pump regulator
