How would I know if its detonating? I've never run into it (I don't think) before on my other car so i'm not sure what to look for. Also, how can I tell what the timing is set at? Thanks for the responses and welcome.
A couple days ago I purchased a 94 stang gt 5.0. It didn't come with an owners manual so when I filled it I put premium in to be safe but I was wondering what octane it runs on (my only mod is a cai).
