fault codes on a newly re-headed supra

[lethalwithasupra]

introduction;
hello every1, nice to meet. had my supra a year and still wont part with it. tho thats a close thing. last night i hated it. this car's giving me a nervious twitch ... 86 mkiii supra with the newer 7mgte engine. as standard as a shot glass 'cept for the slightly advanced exhaust cam.


problem;
blown head gasket is repaired ( the people who replaced the bent valves, planed and ported the head suggested the cam for overlap ), now its idling at 2k ( i think that's because of the timing that im having trouble setting ... light wont work at 2k. had it almost right but went to bring it back a tooth and got confused. its too late and im too overworked ) also its bringing up the fault codes 43 and 51. i am looking, just havn't found a list of codes yet.

51 is an altitude meter and has been there for a while, don't know if it'll ever get fixed. 43 is new. im sure i havn't missed any plugs around the motor but yea ... little help ?
