PLEASE HELP!!!!!!!

Ok so we are working on an 87 runner 22re standard 4x4. it started running like garbage. we pulled the codes and we got;

1. #5 - bad O2 sensor
2. #10 - starter signal
3. #11 - ECU power supply
4. #12 - engine RPM signal

These all popped up in a day or 2. did I do something to cause this? I have heard that the #11 might be caused by to much roll starting. I do roll start it ALOT. I have not really changed anything other than the exhaust after the manifold. It has been REALLY cold blooded since I bought it 1 1/2 years ago. I have a buddy who has an 85 runner with an 87 engine more miles and his starts right up with no issues. PLAESE HELP. thanks in advance.

roll starting? as in push starting it? why? is your starter broken? sounds liek it ul;timately breaks down to a wiring issue

lazyness is the cause for the roll starting.

Wiring issues.  You can try to test, or swap out the O2 sensor and see if that code goes away. If it doesn't than I would say you have some real wiring issues. Could also be your ECU, KDC just had to replace his a week ago or so. From the looks of your avatar it sees some water/mud/crap that gets all over everything, I would start by making sure all connections are clean and clear.
