2003 Z06 code P1415 help
Hello,
1st of all, I am 65 years old and new to Corvette's, and I absolutely love my 2003 C5 Z-06.
I am trying to smog in California and need help. I had code P1415 to which I 1st made sure pump was blowing. Then I sprayed throttle body cleaner and a little WD40 into the hose going to check valve followed by compressed air and repeated a couple times. I believe I loosened the check valve because the code has not come back after about 130 miles and many cold starts. The problem is, the secondary air system monitor is still showing "incomplete" after many more miles and many cold starts. I need to get the smog done ASAP, so any help you have will be much appreciated.
