OK, that eliminates out of phase CMP/CKP sensors.... You can check for a coil problem by simply swapping coils and seeing if the problem follows the coil. You should also closely check the connectors at the PTU and the coils. I've seen the pins get pulled out of the connectors, and not make a connection, even while appearing to be connected externally.

Ok thankz ill check the pins tomorrow right now its really cold outside

Ooooor check the cas. Had the exact same problem after and autox, bought a new coil no luck, did some digging to discover if the crank angle sensor is off in the timing that you will see this oddball issue, sure enough, pulled the timing covers off and I was off a tooth. For whatever reason, the ecu won't fire the coil at all if the crank angle sensor doesn't properly overlap the cam angle sensor

91-92 cars don't have separate sensors...
