    Code 52

    Gentlemen: For your consideration,1994 Shadow,2.5 TBI auto.108k miles
    Runs pig rich, enough to foul the plugs.Ya gotta floor it to cold start it.
    chugs and dies at idle, or surges to 2000rpm.
    tach also reads high&bounces when driving(frisky tach syndrome)
    persistently shows a code 52. has at times shown codes 21 and 32.
    Initially showed purge canister sol fault.
    I've monitored the O2 and it ranges 200 to 1000 Mvdc
    Purge and EGR now disconnected, NO vacuum leaks
    So far: new o2 sensor, temp sensor,idle air motor,HEP,injector,FPR,
    dist cap&rotor. 192deg T-stat
    new fuel pump and filter, system flushed.

    WATZUP WIT DIS TUB-O-SHITE!!!
