Well I took it to another shop and was buzz tested again and cylinders 3 and 8 (dealer said they told me wrong cylinder and it was 3 and 8 as well) are weak. Said they didnt get any codes that showed the UVC's were bad. I got two new injectors for $100 so I just decided to replace them. I also want to replace both UVC's, what are the part numbers for the UVC's and what do I need to replace the injectors?
