I don't think it's exhaust related since it all looks to be in pretty good shape. Also fairly certain the car doesn't have cats but perhaps Johnhef could shed some more light on the topic (forwards thread).

Where is the crank sensor located on M117? How would I test this?

When I replaced the plugs I used non-resistors so I doubt that's the problem.
