P1320 NISSAN -

Question

Answer 1

P1320 Igntion signal

You replaced 6 coils, P1320 means problem with the ignition coil one or more have failed, This code also can appear after a Timing belt installation gone wrong.,such as a overly worn T-belt. You mainly need to do a power balance test you also need to check ECM relay, check ignition coil power supply. Which is the right way to go . Your better off inspecting for a timing belt first. I seen alot of these where a timing belt was the solution.I should also mention fuel pressure check
