I can tell if there has any miss by put my hand at exhaust pipe. I feel those pulse at idle but there has not even been a single one at 1600 rpm. There seems has a gap between 900rpm and 1600rpm. Even a slightly movement on throttle which I put 2 layer of printing papers on the throttle stop screw.I can't turn that screw because they put some locktight. This is a used throttle I bought from ebay but it actting same as my old one so I don't know if both of them are bad. This car use waste spark ignition coil pack so if the coil has problem would cause two cylinders miss and stall the engine but my engine never stalled. I have new NGK wires and spark plugs.
The slowest idle I can achieve is 1600rpm by sticking paper between stoper and lever. The idle will goes to 2200rpm if I stepped on the gas padal. Do you think this could be a bad throttle?
