1999 s420 p0410 Error
Is this code for secondary air system or head gasket? Autozone read the code for me and the said head gasket, but google searches say secondary air system.
Car running rough, but gets a little better when warm. At idle the roughness is much less than when I put it in gear.
Please help.
Thanks!
