I now have a check engine light and several "too rich/lean" codes and ONCE received the AMM 1-2-1 code, which hasn't returned yet after clearing. But I do get codes 2-3-1 and 2-2-1 (too rich or lean).

To check AMM Bentley and Haynes manuals say for LH 2.4 check resistance between terminals 2 (green/yellow wire) and terminal 3 (white/red wire). There aren't any exposed wires to check color so I check between the second and third terminals from the left. Is this correct? The resistance is supposed to be about 2.5 to 4 ohms. I read 42 ohms. So replace AMM? Any other suggestions before $$$ ?

New AMM = $319 @ FCP
rebult AMM = $159 @ FCP

THANKS
