HELP: Need some help with a trouble code(s)

Today I went to get my car inspected and it failed. It had 3 trouble codes

My car: 2000 Ford Focus ZX3

P0751- Shift Solenoid A Performance Problem or Stuck In Off Position

P1120- T.P.S Out of Range Low Condition

P1121- T.P.S. Inconsistent w/ M.A.F Sensor Condition

I know that I have to get the TPS fixed and all but does anyone know about the P0751?

I used to have a Cold Air and 65mm Steeda Throttle Body before and there was no “check Engine” light. But since I went back to stock, the light has been on.

I really need to get this fixed since its New Years Eve and tomorrow will be 2006. If anyone has any knowledge, is willing to fix this (of course i would pay $$) or send me in the right person/business to get this problem fixed. I just need to get this inspected before I get pulled over.

Thanks

anyone?

tell them what it is and what year man :tup:
