Hey guys.........I'm still a green Stang owner........How safe is it if you tap the rev limiter? I mean, I guess that's what it's for but I've tapped it a couple of times this week. Also, my '02 GT has 71K miles.......Do these engines do well when taking a beating at those miles? Anyone ever experience any power loss due to high miles? I've always heard that we don't generally need to change out plugs til 100K miles. How would I know if I need to do that? Is there a code for that? Sorry I keep asking so many questions, I'm just curious.......Any advise?? Thanks!!!!
