To be honest, I can't tell what is currently the issue with your car. I can't recall it all, or haven't read and reread your posts, but you, I, and CFT have some rapport so I will do my best on my time off to help.
I haven't honestly ever heard of a RWD brick running ok and then when hot it takes a dump. Actually, lying, I have, it was the ignition module overheating. I had it happen on a 740 once. It would run fine cold, but then die hot.
If I were you, honestly, I would fire a crank sensor and powerstage/ignition module at it and hope for the best. If your time is worth more than the parts, go for it!
There are basic voltage test you can do to test powerstage, but I am not gonna take the time to research it/explain it right now to be honest. Again, that being said, powerstage causes a DEAD car. NOT misfires. I could be wrong. But I would supsect those two things based on experience and information provided, well at least the information I have processed and somewhat remembered. Car in hand is always best.
I appreciate both of you taking the time to help. At this point I want to understand why the car is having these problems. It is something that will always bother me if I don't figure it out or someone else figures it out and I have zero experience with LH 2.4 or 3.1 so you guys have a big advantage on me there. The good thing is I have managed to keep a lot of Volvos running without any diagnostics as well and based purely off experience and information from a lot of other wise Volvo owners. Hopefully this gets sorted and we can all add it to a known problem to help the next guy around.
I guess there is a reason that the PO and the PO before him didn't get the car running . Amongst the parts my friend brought me there is a good powerstage and crank sensor. I will throw those at it just to see. I need to pick up a new DP gasket as well so I can put the 02 back in the downpipe when I swap it to a earlier DP .
