Thanks. I need the check engine light to be off to pass California emissions testing. I was thinking that since I’ve got a code 51, I’d replace all of the injectors. I could ohm them, but since I’ll have to do the work if getting in there, I thought I’d replace them all. Was tempted by the picture of the Denso spray pattern (it looks more even) and I was tempted by 550cc Bosch injectors. Sent from my iPhone using Tapatalk
