My 84 was a total hot weather problem car. The PO told me it would be, and it was- for years. I went through all the components you mentioned, and more, and what fixed it was replacing the ECU, (the unit by the window washer reservoir). My symptom was bogging way down after long driving in hot weather. It chugged and then wouldn't go more than 10-15 mph until I gave it a rest.

I just thought I should mention another option that didn't get brought up. All your 240's having this problem is beyond me.

I agree with jwalker, that was a good post. Your ties to the marque are explained well.

As a relative newcomer to Volvos, I've specialized in one model series -- the 200. I've heard many attempt to stereotype them in one way or another, and considered whether my experience supported the image. Of the various generalizations made, hot stalling wasn't one I'd heard until your question, and as serious as that can be, it would run counter to the most applicable stereotype I can agree with, and that is safety.

240's are (relatively) safe. They're durable. They rust when the rocker drains aren't clear. Their fuses need attention when their windshields leak. Their tail lights will get you tickets, not their awesome horsepower. They are uniquely suited to shade tree wrenching -- you don't need factory software downloads to change a module.

The hot stalling, I think, is an individual issue, and not stereotypical.

Obituaries would be a lot more interesting if they told you how the person died.

Good post!

If you do take the preheat hose and the airbox flap out remember to cover the opening with something to keep the mice etc. out. I used a woman's nylon...:)

BTW - my 95 850 has never stalled or died on the road either. Knock on wood..
