P1312 with New IDM

I am troubleshooting a code P1312 on a 2002 9-3 SE 2.0. Replaced the IDM and spark plugs with the correct NGKs. Still getting intermittent P1312 although the CEL went off yesterday after I removed the plug on the IDM and replugged it. The contacts on the plug look fine. I am suspecting an intermittent connection problem somewhere but I haven’t gone through the complete diagnostic procedure yet in WIS to see what that may reveal. Has anyone else experienced something similar? It seems all the posts relating to P1312 have been solved by a new IDM. I will further research this in WIS but can anyone save me some searching if they know where the other end of that IDM cable is? I am not sure what I am looking at when I compare the banks for cylinders 1 and 2 to banks 3 and 4 on the Tech 2, but there does seem to be some difference between the shape of the graphed peaks between the two banks. This code refers to a combustion problem with 1 and 2. Of course, the car seems to run fine in spite of everything! Thanks for any advice.
