My 940 manual lpt runs rough (link to video of car runing) and vibrates a lot at idle and even more at 1500rpm. I've changed plugs, cleaned PCV, changed all filters, ran injector cleaner, etc.
The car does have a crack both on front muffler and cat, but why would it only vibrate at idle and 1500?
I'm suspecting a dirty MAF or distributor issues but i really dont know. What do you guys think?

Seems worse when it rains and today the engine cut out in the morning while idling cold.
