1. Had 3 injectors fail and 1 was boarderline, so I replaced all 6 injectors. Adjusted the valves. They seem a little louder than before. It sounds like valve chatter. The shop says that is normal since the injector changed from a 4 hole to 5 hole injector. These are stock replacement Bosch.
2. The other weird thing is in park I raised the rpm around 1500-1700 and it has a lope that goes away any higher or lower than that. I dont feel it when I drive.
3. I noticed on my overhead mpg are down about 2mpg's. I didnt hand calculate it before the injector change so i just use it as a referance.

How does that sound?
