For some reason cosde 45 keeps poppin up on my dash . Changed oxygen sensor and then i noticed my choke wasnt working so i changed that . All original parts by the way so i thought it would be ready for smog but still i seem to have same problem . Code 45 means it is running too rich . I was going to check out the car but i dont have time . My car is all original by the way 305 v8 brougham LS . I am new to the gbody forum and maybe you guys could help me out a little. Thanks
