Hi Guys, Just seeking some advice. I have a 2002 Corolla Levin and on occasion I am noticing the idle dropping and idling very rough for a short period of time, I have also noticed on occasion when I first start the car it is idling quite high for a period of time. I don't think this is normal as when I say idling high I mean like over 2000 rpm to me that is too high. I have been advised to check - 1. Throttle Body 2. Injectors 3. Spark plugs Any advice with the above would be greatly appreciated. Regards Shane
