What engine parts are these?
Finally got curious enough to ask. I have some idea what these little items are, but it'll be good to know for sure:
Red arrow: No idea, really. It has three elements that look pretty much the same. My "wild guess" is the fuel pressure regulator.
Green arrow: Not sure. Vacuum line? EGR line?
Blue arrow: TPS (Throttle Position Sensor)?
Yellow arrow: line for the idle air bypass? (connecting to the intake elbow)
So... who knows their way around LQ1s?

Red is EGR Valve
Green Vacuum to upper plenum, cant recall exactly where from
Blue is Idle air control valve
Yellow is just a plastic vent tube, again can recall exactly from where
Its been a while since messing with 3.4 dohc

I remember that EGR from the days of the early 3100's. On the 94/95 Grand Ams, they had issues with that thing popping codes. Sometimes you could simply clean up the carbon gunk build up and other times, not so lucky.
