I'm throwing the P1136 "system too lean code"
My check engine light came on about a month ago then after 4 days it went off. I had someone vag my car anyways and it showed two fault codes, P1136 and P1559. Now my check engine light is back on and I'm assuming it's the P1136 code. What could be causing this on an AEB engine? From what I searched it seems a vacuum leak can cause this or an oxygen sensor. What oxygen sensor is this? Thanks!

Pre-cat sensor is easy as pie to replace and cheap too for a '97

The front sensor is here, right?
