THE ENGINE WOULD MISS BY HAVING A LOW VIBRATION. NO NOISE WOULD BE MADE. WHEN HAVING A BAD PLUG THE RPM TACH GAUGE'S NEEDLE WILL FLUXUATE. IF THE PLUGS ARE GOOD THE NEEDLE WILL STAY STEADY AT AN IDLE

Pull the spark plugs and see if coolant comes out of the spark plug holes when you turn it over by hand. If it does than the upper plenum has ruptured and will need to be replaced.

Make a little engine noise and shake a little.


Change spark plugs After checking. Open hood in the dark of night and look for sparking
along the plug wires and at the spark plugs themselves. If you can see sparking (or hear it) replace the wires.

Check the spark plugs, on cyl#1 if the problem started after they were replaced you could have a defective plug. As for the metal to metal noise have your brakes inspected. They could be worn out.

The car has started to shake when idle, with a faint banging noise


It's probably either a faulty spark plug, or spark plug wire, or a sticking valve lifter. I can't hear the noise, but if it's a tapping noise, it'll be a lifter. Try going to any parts store, and getting some engine additive. There are dozens on the market, but a cup of transmission oil in the crankcase will do the same thing.
If it's not that, then replace plugs and wires.

Oil in the spark plug well on one plug/ back left


you are going to have to replace the valve cover gasket, the seal around the plug wells is leaking.

You either have a bad plug wire or have cracked one of the new plugs while installing them. Try watching under the hood while someone else accelerates the engine to locate the noise.
Good luck dont forget to rate.
