took Ginger out today...codes

[tery]

In anticipation of putting cars in storage I took Ginger out today to use up some of the gas and...it's a beautiful day here...anyway, got these codes...I think the've all been there before but anyway..Any worries??

172
176
332
543

Also strange little light flicker for about half a minute from the dash clock...
I still need to replace her temp sensors, Comparing to my other cars, I just don't think they're working right, too much changing and not showing temp when I know the engine is warmed up. I think in the spring, I'll do the stat and the sensors..

Do I need to do anything about these codes right now She's going into winter storage in two weeks.
tks in advance,

543 = fuel pump secondary circuit - ignore this as it gets set if the motor stalls.
332 = egr opening not detected. you will want to fix this as it results in a cel on from the first point the egr valve should open each time you start the motor. it is nearly always the ports in the intake that are plugged, not the egr valve.
172 & 176 = lean on each bank. nearly always this is due to oxy sensors that need replaced, but it could be a significant vacuum leak on the intake somewhere.

yes, you need to fix the last 3.

thank you Fred, I remember getting that EGR code now. I'm putting these items on a list for the spring, they don't need to be fixed to sit for 6 months and now that school is "on" I have very little time for anything. I did give everyone a bath and shine today in anticipation of the upcoming hibernation. I need to go get rat poison and that marine grade stabile. I'm taking them to rest in 3 weeks, but will get very little if any drive time before then.
