Thanks, I'll have to check that out. It's interesting that it says bogging when the AC is on. I have 2003 Ford Focus SVT that has variable valve timing on the intake side and it does that bogging when the AC is on. I wonder if it has a similar problem. I changed the timing belt on it last summer and from what I remember the variable timing unit looked a lot like the VANOS.

Also, have you guys had any trouble with your DISA? I'm thinking about doing the VANOS seals and the CVV fix as a winter project, and I'll probably take the DISA off and have a look at it too. My SVT has a variable length intake with a servo motor controlling it. I think the DISA is meant to achieve the same result.
