    p0308 intermittent

    I appreciate the offer. So far since the start of this thread, the CEL has not come on (hopefully I didn't jinx myself). I just ordered all the stuff to fix my manifold studs (resurfacing existing manifolds, new OEM gaskets, and studs) and will be tackling that job next week. This way that...
