got some codes...
it went like this...
4 1 1 4 1 6 6 5 2 3 4 7 7 5 2
so I think that means I got codes
41 ... MAYBE I miscounted?? because I dont see a KOER code 41...
34 PFE or EVP above closed limit of .67 volts
66 TOT sensor output was less than Self-Test minimum value of 0.15 volts.
52 OPERATOR ERROR
77 OPERATOR ERROR
I Dont understand what 34 or 66 actually mean... if they're important... or if they are worth fixing?

I think you rec'd 4 flashes for the 8 cylinder engine, just a routine code.
Then 11 for Key on, engine off test(KOEO), which means you passed. Then a brief single flash meant the stored codes were coming and you may have added that to a real stored code of 31 to get a false 41, 31 code is EGR/EVP related. 34 is EGR/EVP related, 52 means you didn't turn the steering wheel during key on engine running(KOER) and 77 means you forgot do give the engine gas during KOER test. The 66 could be related to 31 and 34, because you may have a broken vacuum line in the system.
The three codes I think are correct are 31 34 and 66, all can be caused by low or no vacuum at the proper sensors.
I was getting 31 and 34 all winter because the coffee-can looking item on the right well wheel(which is actually a vacuum reservoir) had a hole in it. I had a vacuum leak, and it affected the solenoid that opened and closed the EGR, thereby giving me a bad reading at my EGR sending unit.
