I have an '84 944. It just started stalling a couple days ago. The first time I was at a stop light and it just died. It would restart but die again within a second or two. After about 5 restarts it kept running. It ran fine for a couple days. Now today I shut it off waiting for the ferry and when I tried to restart it did the same thing and took several tried to keep running. Then it stalled a couple times while driving. I just left the clutch out to keep the engine spinning and it recovered after 5 or 10 seconds and ran fine. It also has an occasional misfire at full throttle but it is random. Where is a good place to start?

 

Boy, could be a bunch of things. I would check to make sure you have good spark and fuel pressure first. If those check out ok, then I would start by replacing the DME relay and drive it and see what happens. After that, Reference sensors, DME temp sensor, and AFM is where I would look.

 

I haven't had a chance to do any testing on it yet. Yesterday the problem got really bad. The engine kept cutting out and lurching real bad. It quit for about 20 seconds at a time several times.
I gave the DME a few good whacks today and it hasn't even studdered since so I am thinking that might be the problem. (drove about 80 miles today)I am probably going to pull it out and resolder it like mentioned on the clarks garage website.

 

A good whack always works....until it needs another good whack!
