I bought this car with a bad engine found a very good used n/a from a 1994 legacy tried to find out before I started to see if this will work got no replys so I installed engineall the sensors seemed to hook up & looked the same hooked them up I had upuged the turbo sensors & got the engine started didn't run well & got CEL hooked them up it seemed to run better but not right when I start it idles 1800 to 2000 rpm after a couple minutes it will slow down but then start to lope probably because its running rich I tried a used ECU from a 94 legacy n/a 5speed M/T now it will not start My question is would an ECU from a 91 legacy n/amake it all better? the codes I get are 21-31-45 but they do not set the CEL if I clear codes run the engine the same codes are back HELP ![/list]
