no it wasn't. i changed sparks plugs, and valve covers gaskets. the car is not overheating , just idling too high and shaking.
I would say it still has a vacum leak. The best way is to spray around the intaker and all vacum lines and the intake and throttle body. When you hit the leak you will hear the change in idle

spray what?
spray around with carb cleaner spray around all vacum lines the intake and the throttle body and the air intake duct with the motor running when you hit the leak with the spray the idle will change, pinpoint the leak and repair it
