Well I'm new to this site but I have a question.....can anyone tell me what could possibly be wrong with my car. When I start it its fine but a few minutes after well when not in motion it makes this noise as if its going to die out and my rpm gauge goes crazy i dont think its the clutch because when i drive it its fine and everything is smooth my car is a 1987 crx si can anyone help? any help is greatly appreciated.

Well sorta But if that may be it i'll do that this week. But yesterday I changed the head and valve gasket because it needed both

 

Well sorta But if that may be it i'll do that this week. But yesterday I changed the head and valve gasket because it needed both, put in new spark plugs, and changed the oil i thought that would solve the problem but apparantely it didnt any other suggestions? Thanks for posting
