Thanks smolck. I was really hoping it wasn't that or the CCV - but I know your experience with these cars and I'll trust that it may be that.
I am relatively handy... How would you compare difficulty versus OFHG or VCG, or DISA (all of which I've done)? I'll search DIY's for it too and assess for myself, but it would be nice to know your opinion as well.
