I have a 2013 RDX with 103 miles, just changed the plugs, starts ok, giving me a flashing engine light, and lots of error messages:
Check VSA Sys
Check Emission SYS
Check PS Sys
Electrtic PS 85
engine sys PO305
Vehicle stab assist 83
Hill start sys

I checked the conn on the elec plug for the spark plugs, all look ok.

Did I bump a sensor or major connector, OR???

Thanks,

Did you use oem spark plugs?
Did you use any anti-seize on the threads?

I would be concentrating on P0305 first, it says cylinder 5 misfire.
If you used OEM plugs, try the old one in Cyl 5 to see if the P0305 goes away.

As above, check the plug on cylinder 5 . Pull it out and see if by chance you might have changed the gap when installing it. May be a bad plug , or the connector from the coil isn't right. After changing it out and you still get the same code, swap the coil from another cylinder and see if the code changes to that other cylinder, if so, it's telling you that coil is , or going bad.
