Time for an update.
I continued to have problems since my last post. I wasn't convinced that it was just the #6 injector so I kept driving it to see if it would really act up again and it eventually did. At that time I ran the diagnostics again.
Long story short, I had all sorts of codes relating to the even numbered injectors (left bank) and IDM codes.
I decided to order a high voltage/freq IDM from Swamps. I put it on last night. When I took my old IDM out I noticed that it was full of water. After I put the new IDM in, the van fired right up and seemed to run pretty well. Much better than it had been at least.
Problem is, I still don't think its running perfectly. I ran the diagnostics this afternoon and I got a whole new set of codes.
KOEO and Buzz Tests
1271,1272,1273,1274,1275,1276- cylinders 1-6 high to low side open
The injectors make the same noise during the Buzz test. They have equal volume and tone.
P0278 cyl 6 injector circuit contribution/balance fault
So basically I still have that same cylinder 6 fault as I always have. Maybe a bad injector?
The weird thing is now I have a problem with the right bank which I never had before. The only change was the new IDM. Any thoughts? I definitely think my old IDM was bad, but does my new one have problems too, or more likely do I still have some other electrical problem.
