Just replaced timing belt and water pump on a 98 civic dx engine d16y7. Car starts and sounds great but after engine warm up and in park idle goes up down and continues this .Took for a drive and runs great but idles a little high in drive.Put in park idles up and down and continues this.Could this be something with the coolant or cooling system.
