Think this engine has had its day,could be a hydraulic valve adjuster ,well the noise anyway but as for the rough idle i have no idea without my head inside the engine compartment

Service engine soon light on and car runs rough and stalls at idle speed


if i were you i would start with a fuel filter, if that helps, but its still not quite right, replace plugs and wires also, basically a general tuneup of plugs, wires, fuel filter, air filter, will most definately fix your problem.. the fuel filter alone may.. hope this helps
