Help, My engine warning light is coming on intermittantly. How can I find out if this is this serious? My Forester still drives like a dream.

Welcome to the forum. Typically most autoparts stores can check that and tell you what the code is.

What year car?

nevermind...saw it in Lizzy's public profile.

The codes are P1090 and P1088. I've been told an oxygen sensor needs replacing. Is this right? Can anyone do this? Will it be expensive?

unfrort the subaru o2 sensors are expensive, depending on where you source it from, it could cost upwards of $175 bucks...
