We got a check engine light about 2 months ago and after reading codes and some research determined it was most likely the O2 sensors. I do most of the mechanical work but due to access of these sensors I took this vehicle to a shop. They did a diagnosis and said all 4 sensors should be replaced. That did not clear the check engine light so they did a lot more diagnosis and still could not find the problem. They wanted to replace the ECM, but we declined because you can get into a replace this, replace that and it gets very expensive. The current codes as of today are following:
All preceded by P O 135, 141, 155, 161, 403, and 443.
Also, during this time, there was a short time where the battery would be drawn down and to start it, I would have to jump start. This was only an initial startup in the morning. I have checked all the fuses and found none blown. I am not sure if any of the relays are bad.
Anything you can suggest would be greatly appreciated.
Thank you in advance for your help.
