91 940 Turbo. Starts fine, fickle idle/run

Post by BucklesJohnson » Mon Jan 27, 2020 7:17 am

I'm not exactly car savvy and I'm hoping to get a diagnosis for work I can (possibly) do myself, or point someone in the right direction.
My car wouldnt start yesterday. I isolated the click noise to the (red) circled box in the picture, pulled the (green) circled items out and put them back in as they came out.

Now it starts ok but has an extremely weak idle and will die if idled too long. I even hit a bit of a bump in the road and it died too. What are these things, what do they do, and why is my car doing this? Any help appreciated. Thank you.

That appears to be the ABS module.
