Gentlemen:

The only hting I did was swap my kompressor this weekend. Oh I installed an aftermarket converter 2 months ago.

I am getting the following codes since yesterday. I cleared it using a cheapie scanner and they came back.

From searching the archives it seems that a vac leak may be occuring. I will get under there tonight and root around but I wanted to pick your collective genius brains.

Thanks.
