Per my scanner I am receiving a p1320 code. Looking up info I found all these items that could be causing the problem. Malfunction is detected when ECM does not receive signal from ignition primary circuit during engine cranking or running. Possible causes are:
Ignition primary circuit open or shorted.
Defective power transistor (integral with ignition coil).
Defective Crankshaft Position (CKP) sensor (REF).
CKP sensor (REF) circuit open or shorted.
The weird part is I just replaced all the coils (because I got a code for coil 3 being bad) and the car runs great, but this code pops up. Doesn't quite make sense.
have the same problem?
