99 Deville and 91 Eldo code help!

[bschelle]

My 99 Deville w/109,000 gave me these codes:

P0122

P0300

P0741

P01122

P01381

I was able to decifer them but I am clueless as to what caused them. It did run like it was firing on only 4 cyl. but cleared up and it is running fine right now.

Also, my 91 Eldo w/107,000 gave me these codes:

E047

B121

B333

B334

B335

B336

B337

B552

I did just replace the heater core so I understand the voltage codes but what about the rest?

Thanks in advance!

Was the battery disconnected before the heater core was changed? During that procedure one had to remove all the computers including BCM. I would clean the codes to see if they return. Disconnect and reconnect the connectors to BCM to make sure they are good.
