understanding codes
Ok, heres the story i have 2002 Z i have only own it for 3 months , i just deed a headers x pipe with cats swap. after the install the check engine light came on which is no suprise but i dont remember if the services vehicle light came on so anyway i had the car tune, then about a day later the service vehicle soon light came on, so i did the procedure to find the code, so heres what i am having problems while the car going through it i notice two things one code was B0446 C from what i have been reading C means current, after the cycle was finish it says 10-PCM code 1 which lead me to p1637 H, h means history i clear it but its still coming back so between those 2 codes i mention which is my current problem? any input would be appreciated thanks
