i am new to third gens and i was driving the other day and the ses light came on. pulled the code got code 15 bad cts. replaces the cts and im still having problems but now the car wont idle and is running rich. does anyone know what else i need to do to fix this. the car is a 1992 rs v6.
thanks

 

did u clear the codes and do an idle relearn?

 

i did clear the codes, but i still am getting code 15. i think there might be a bad ground somewhere. i am going to try a idle relearn later today.

 

so after doing an idlerelarn i am still having problems and the ses light is still on with code 15. i have made its own ground so i know it has a good ground and i have disconected the battery to clear the codes but it still comes right back on. is there something i am missing?

 

 

i am using the bridging of the ports with a paperclip. thats the only method i know of. i think i might have finally found that it was a bad connector on the cts. i have made a test connector and the ses light is now off with it and the car is running close to normal i think it just needs a good tune up and maybe an idlerelearn.
