I'm not 100% sure about that. I just rely on what my computer fault codes tell me and sometimes it's lean or rich. I got lean this time. These are actually the codes I got last time I checked:
12-battery disconnected recently
32-computer didn't see change in air/'fuel ratio when EGR activated - check valve, vacuum lines, and EGR electrical
11-No ignition reference signal detected during cranking (bad Hall effect)
OR timing belt skipped one or more teeth;
OR loss of either camshaft or crankshaft position sensor
51-Oxygen sensor stuck at lean position
55-end of course.
So.I'm putting in a used O2 sensor today to see what happens because I don't want to put it a new one until I know what's going on. Thanks for helping me though, my dad's a mechanic of 40+ years and he doesn't know what it is either.
