Try to make this not a long story but I just got this 92 Talon TSi had it running good on ECMLink. Then the car just started running horrible, I never got to drive the car only idle tuning. I verified base timing but when I set it to 5* the car barely ran and wanted to die. Today I checked cam and engine time, it was fine. I then checked the CAS and it was backwards. Put it all back together set timing to 5* and car still ran rough but didn’t want to die like yesterday. I then found out #4 cylinder isnt firing. I checked spark at plug it’s fine, compression check 170psi, swapped spark plugs around, swapped around fuel injectors, new plug wires and still misfiring on #4. I probed the injector and it is firing and I can hear it clicking. I didn’t check again but when I pulled the plug the first time it was dry. When I pull out 1-3 spark plug wires they keep arcing, but when I pull #4 it doesn’t arc. Is it a bad coil? Are the wires supposed to keep arcing? I didn’t gap the new plugs yet but would it really be blowing out the spark at idle especially when it was running fine before? I think I read that these cars are batch fire ignition so could I swap the #4 plug wire with I assume #1 and see if it switches from 4 to 1 misfire?
