Ok I have a 98 kouki KA Motor/5 Speed with about 30,000 miles.At cold start-up my idle will drop as low as 300~400 and then I will have to press the gas once then it'll raise back up to normal idle I Just changed the spark plugs,wires,oil, and air filter. But it still does it. I haven't changed the fuel filter yet but I am thinkg of it.
If anyone has any suggestion on the problem please post thanks
