Hi
After endless search of the vacuum leaks and stuff I Finally got my car back in starting shape. Yes there was a minimal vacuum leak on intake manifold where the idle airhose is connector is pressed on manifold. It helped a bit. The car is still ill. :-(
I checked the injectors classic hayness style when idling and unplugging the connectors on injectors on cylinder 3 and 4 had no effect on my idle.
It seems that there is voltage as specified and injector resistance reads 2-3 AS it it should.
Any tips how to further anylize the condition of the injectors.
cheers,
marko

The fuel injectors are driven by grounding through the DME. The #3 and #4 injectors are wired together and are driven by pin #14 of the DME. Pull the connector off the DME and test for electrical continuity between pin #2 of the #3 and #4 injector connectors with pin #14 of the DME connector. As a double check, #1 and #2 injectors connect to pin #15 of the DME. If there is no continuity, you have a broken wire inside your engine/fuel injection wiring harness. This is apparently the usual cause of losing two injectors at one time.
