# 3 cylinder miss firing

939 Views 6 Replies 5 Participants Last post by  Pete315
I have a 2000 STS and my service engine soon light is on. The code says the #3 cylinder is miss firing. I've changed the sparkplugs, coil and injector and it's still miss firing and reading the same code. Does anybody have any suggestions? The car idles a lil rough but drives fine when on the road. I can definitely feel and hear the missing!

could be the wiring for the injector. I had to replace my fuel rail wiring which fixed my problem.
