I think everyone got tired of spelling everything out, so if you just 
joined, it looks like a military hand book.  Here are some of the common 
ones off the top of my head:
	TPS:  Throttle Position Sensor
	MAP:  Manifold Absolute Pressure
	MAF:  Mass Air Flow sensor
	BAP:  Barometric Absolute Pressure
	CLT or ECT: Engine Coolant Temperature
	IAT:  Intake Air Temp.
	O2:  Exhaust Oxygen Sensor
	HEGO:  Heated O2 sensor
	ECU:	Electronic Control Unit
	EEC:	Electronic engine controller (Ford)

It is a good idea to compile a list new people can access.  I just 
joined a couple of weeks ago.  Maybe there is one somewhere.  Anyone 
care to comment?
