Like the title says. I changed my broken valve spring that i thought was the problem but Im sill getting a misfire from the same no 5 cylinder. The car sounds a little rough at idle and smooths out when im driving. Seems to have its power back although I didnt want to beat on it too much. speedo was jumping around at some points and one time it felt like my trany was slipping but didnt do it again. If anyone could tell me what might cause this, Im tired of not having my car on the road.
