Maybe the engine just needs a tuneup. Check for vacuum leaks and use a good fuel system cleaner.

Cap and rotor? I'm sorry I am a carpenter/ remodeler so forgive me Google is training me... I had a fuel line upper that was cracked I replaced it because it dump fuel into my number 1 and 3 spark plug holes I'm hoping is not one of the three coil packs a couple of people told me it sounds like a vacuum line leak so I'm trying to figure out the vacuum line system now
