Help in deciphering engine codes from 1991 Coupe

[Luke Perry]

Hi, this evening my check engine light came on in my 1991 780. This
happened after a few minutes of driving and a slightly harder than
normal stop followed by getting up to freeway speed. The car seems to
driving normal with no starting or stalling problems (so far).

Here are the codes the computer gave -

2-3-2

2-3-1

2-2-1


I used to have a 240 that had issues after the check engine light came
on. The problems got progressively worse and the issue was finally
traced to a bad O2 sensor after many bad diagnoses. Is anyone
familiar with the 700 series who have had the same problem with the
check engine light and similar codes?


thanks

These are the classic vacuum leak codes. Also commonly caused by fuel
pressure.
