Got a smooth idle again without changing the *motor mounts, I think they are still fine for now. Did get some new engine shocks and will replace those soon to protect the expensive mounts.

Got new Bosch copper H9DC, gapped at 0.4, used to gap them at .32. makes a difference in idle and response. Furthermore installed a new New Oil pressure Sensor (VDO), accurate reading now, don't cheap out. New 4 pin coolant temp sensor (Hella), broke in two pieces when I took it off and changed the small fuel filter at fuel distributor, what was definitely needed.

Saving some money with no need for new motor mounts, I can spend now on a re-dye of the interior.
