So I've been getting a CEL on my 94 that will come on and go off while driving.
I changed the fuel cap but still get it occasionally. Also get a smell of gas once in a while.
I decided to pull some codes via the CEL with a jumper on the EEC.
Code 136 or P036 a couple times while engine running (Lean bank #2).
What's this telling me?

Key off I get codes:
189 and 176 both indicate fuel rich bank #2.

Where do I start to rectify this problem?
Thanks in advance.

From what I've been reading it sounds like a bad 02 sensor.
Also get some pinging going up hill on the highway.
