Paul,
Before I commit some sort of barbarity, let me make sure I understand what you are saying. So what I see, after removing the epoxy seal, as a slotted, big screw head, is actually a type of hollow, cylindrical plug with screw threads all around it, right? Now, if this already has a slot in it, why should I make one with a hacksaw, or do you mean, make it bigger so I can use a bigger screwdriver? Does the range screw already have a slot in it, or do I need to make a slot in that as well? Sorry to be such a bore with these questions, and this will, probably, all become self-evident once I get into it, but I'd rather look stupid now than later. Of course, I'm still wondering how I can get the full load stop to budge, which it has so far not shown any sign of being willing to do. Maybe soak it in PB Blaster after I have the map sensor casing apart? Thanks for the help.
