The P1355 DTC means the voltage at the primary winding of the rear ignition coil is "out of range" high. This out of range voltage occurs when the ECM tries to fire the coil by grounding the Y/BE (yellow with blue stripe) wire that connects the coil "C" circuit to ECM pin #11. Four things can cause this:
- a short to voltage on the Y/BE wire
- a bad ECM
- a bad coil
- a bad piggyback device
Since you replaced the coil and removed the PC you only have two other sources of the problem.
