Let's see if I can make this make sense...
Injector #1 has an extra "banging" on the line. The vibration seems to be the same as the rest of the lines, but there's a definite bang on the line. I really wouldn't suggest it, but if I were to hold an egg against it, it would probably break it, it hits pretty hard.
What should line #1 feel like? Just a little vibration, maybe a little more than the rest? I gotta go to the dealer and get comp. reprog. for larger tires, I'll have them do the kill test at the same time.
The engine got louder at about 30K and I just thought it was finishing up breaking in and changing its noise. At the same time fuel economy went south, but that's when the weather turned colder as well. I just figured it was all just normal, then about a week ago or so I started feeling the lines.
Oh yeah, no smoke at startup, except when I don't plug it in.
