WE HAD PO300 & P1320. SO WE CHANGED OUT THE SPARK PLUGS & COILS. BUT IT SEEMS TO NOT WANT TO CLEAR OR GO OFF. WE HAVE SNAP ON MODIS AND WE DID WHAT IT TOLD US TO DO. BUT LIKE I SAID THE CODE P1320 IS STILL THERE.
HOW DO WE FIX IT. THE CAR DOES RUN, RUNS GOOD.
Do you
have the same problem?

WE HAVE CHECKED ALL 6 OF THE COILS CONTINUITY FROM COILS TO ECM. THERE IS CONTINUITY AT ALL 6. THERE IS 12V AT START.
NOW REMEMBER WHEN I FIRST GOT THE CAR IT HAD P0300 & P1320. THE MODIS SAID THAT IF THE CAR DOES NOT PICK A CYLINDER OUT TO REPLACE ALL COILS. SO WE REPLACED ALL COILS WITH OREILLY ONES BUT IT STILL HAS P1320. OREILLY BRAND IS BORGWARNER. DO THINK THAT THAT IS THE PROBLEM OR WHAT?

What happens when you clear code? Come right back on start up? Can you go to Mode 7 and drive test?

Out of ideas all that is left is PCM not sure if Borgwarner coils make a difference but some cars are real OEM needy.
Looking through TSB found one on Code P1320
Bulliten ITB01-053 Date September 10, 2001 says if wiring checks out then replace coils with
RH side 22448-31U01 or 22448-31U11
LH side 22448-31U06 or 22448-31U16
Hope this helps
