help, cleared these codes from OBD A6, 411 314, as I was getting retest (smog) the check engine light came on. It seems to have come on when the tech was hooking into to electrical syustem or attaching to plug wire .
I know that A6 is for the ignition system, 411 shows solinoid STH ?
314 said sports mode ok.
checked codes again 411 was there and I cleared before checking for 314

THey will not give me my smog cert, very frustated .I go though this every 2 years, car runs great
volvo 850 1993
any Ideas
thanks ahead of time
