guys, i got a problem. i changed my plugs, wires, and fuel filter. after changing each one, the car ran better for a while, then started running rough. when i first start it in the morning if its cold it makes a whining noise, but other than that its fine. after driving around at operating temp., when i come to a stop, it idles rough. when i put it in park, it clears up. any suggestions? thanks in advance.
