Hi, I have a 2005 mazda rx-8 and it takes me forever to start my engine. My spark plugs are new, my battery, alternator and starter are good. When I finally get it on I cant accelerate then my engine light comes on. I have to park my car and restart it again. After wards it just has trouble accelerating. Can anyone help me?

 

does the check engine light flash under load? how many miles? at or mt? did you replace the coils and wires with the plugs? mods?
