I cleaned VANOS solenoids and MAF sensor because of rough idle on cold start.

After putting VANOS solenoids back in and tightening them I forgot to clip the thing back in so the idle was REALLY rough and I turned off the car after a couple of seconds.

Clipped both back in and now I have service engine soon light, took it for a spin and still have light on.

Computer screen says all systems ok and no check engine light? Car seems to drive ok but still may need new solenoids. Has 51k miles.
