Fully warm the car up. Disconnect the TPS connector. Go drive the car and see if it's the same or not. Leave the trail coil assy disconnected for this by disconnecting the small four wire white plug to it.

 

I'm having the exact same issue. Ill try out the info here and see if I can get my 87 TurboII running tomorrow

 

so what was the fix im havin the same issues

 

So you're getting spark on one of the trailing plugs but not the other. How did you arrive at this specifically? If this is the case then switch the plug wire and plug from the side that is not sparking to the other side of the coil bore that is sparking and see if it will spark or not as this will help to eliminate a suspect plug and or plug wire. You could also switch plug wire and plug that is sparking to the coil bore that is not sparking and also check for spark.
