Dont have to be an OBD2 expert to read a FSM. I however own a code scanner, and am quite familiar with OBD2.
First code is an easy one, if your wiring is fine, you need to replace your rear O2 sensor. I have one from my perfect running 96 i will sell you for cheap. If you want it send me an email,
[email protected].
Second code is a PITA. I hate, hate hate hate hate hate, the evap emissions system. In the early years, our cars were plagued with OBD2 evap problems. This one might not be a bad one however, its a valve that is easily accessible, its near the fuel tank on the car. Im pretty sure you just need to replace it. I have one of those as well if you want it, thats in perfect working condition when i disabled my Evap system.
If your interested in any of this stuff, like i said just shoot me an email and we can work something out. I could even walk you through fixing your codes if you buy my stuff ^^.
