I got running really fine idle is down to 700 rpm, now I'm dealing with 3 error codes 1- 112- ACT sensor circuit grounded or reads 254Â°F, 2 511 - EEC processor ROM test failed, 3- 565 Canister purge circuit failure. 1- I replaced the ACT, temperature gauge is working fine with both ACT sensors check engine code is still there??? 2- 511 code is supposed to be normal when computer is chipped. 3- The canister was working before engine swap. I took it out and tried cleaning it and tested it seems dead.
