Re: problem code p1320 came up on my diagnostic
Sounds like one of your ignition coils are starting to fail, try and find a good price for all 6 on ebay
MIL (check engine light) "ON" with DTC P1320 stored in the ECM Intermittent spark knock (detonation)
Check the ECCS wiring harness for a broken or damaged wire.
- If the ECCS harness has a broken or damaged wire that is causing
the symptom(s) noted above, repair the harness and verify the incident
is resolved.
- If the ECCS harness does not have a broken or damaged wire
and is NOT causing the symptom(s) listed above, proceed with step 3
below.
Replace ignition coil(s) with the one(s) listed in the Parts Information table, and verify the incident is resolved.
