I now have the intermittent loss of power, falling tach, stall, then easy restart after a minute or two scenario on my b230f regina 93 944. Having already refreshed the fender grounds I replaced the RSR with no change in symptoms. I also cleaned and tightened connections from coil to power stage and swapped in a junkyard one with no change. Further testing of those passenger fender grounds reveals 2 ground wires entering the harness and heading to the rear of the car that show very low resistance to ground when disconnected from the fender grounding point and one wire that appears to be heading to the front of the car with infinite resistance. This doesn't seem right to me.

Other possibly unrelated details:

-headlight relay hot to the touch (tried another one - hot too)
- occasional lurching while in cruise control mode at highway speeds (worse after wet conditions)
- engine starts immediately when cold or hot (except when it stalls as described above)
-acceleration normal
=block mounted distributor
-fuse block connections show no signs of corrosion

Any thoughts before I open up the harness to find out where that ground wire goes?
