2 2 1 code. Suggestions welcomed.. 900 1993

posted by  someone claiming to be Dr. Chip on  Sat Mar 19 09:21 CST 2005 [RELATED]

Recently got Check Engine light when driving. After restart, no warning light. Went for 2 weeks, light re-eluminated. Code was 2 2 1
Lean situation, vac leak, low fuel pressure, possible AMM failure. There does not seem to be any rips in the intake hose. No obvious vac leak, except that my A/C diverts to floor under load. Had issue with oil smelling faintly like fuel. Changed the FPR 2X (first one leaked at the fuel rail),

Runs rough at cold idle, MPG down.

Any suggestions before I order a new AMM? Don't have volt meter

93 945 NA, Bosch.

Thanks

Chip

    With the statment that your ac reverts to floor under load,I would say that you have a vacuum servo gone bad and is allowing air into the system. A vacuum leak, find the servo that is leaking and plugg the vacuum line feeding it and then reset your codes and see what you come up with.

      Hmm. Another Chip.... Fantastic (mid 40's ish kid from the NYC metro area too?).
      Can do. The vent redirect has been going on for a few years. I have tripped the computer and seen the code before. Perhaps I can stopper up the vac line heading into the firewall.

      It has new O2 and knock sensors..I do suspect the AMM or some other glitch.

      (BTW. I do know how to spell illuminate...)

      Thanks
