PS: I feel this was all caused because of that down shift to slow down on that hill. Never had any problems out of it before this. 2003 sport, 120k miles. All fluilds and plugs changed at 100k... Ran great until today. Starts fine now just misses non stop while running. Pretty sure it's making a metel on metel noise. Could just be because it's missing. Don't know if something is broke in there? I know all the little things to change to fix this... Plugs, coil pack, ect. Looking for worst case here? Engine rebuild or what? What is the most expensive thing that it REALLY might be? I'm not even close to rich and need my daily drive. No backup.
