I just bought an 87 GN a couple months ago and I am new to the quirks of these cars. After sitting a couple of days when I first start the car the engine idle will hunt up and down almost killing the engine but once the engine is warm it idles at about 2100 rpm fine. Is this normal? Also notice alot of condensation from the exhaust pipes. I am currently buying all the filters and fluids, plugs to go through the car for a good spring clean up. Car is all stock has only 42000 documented miles and a new coil pack and last owner said wires are new. Just want to get it right before I start driving it. Thanks for any help you guys can give and advice.
