Sorry for not being able to reply but yes, it is exactly THAT, the car is not hard to start after being left over night. It is a hot start issue. About 2k miles ago I had the timing chain replaced and at that time the mechanic told me that my plugs were like new. But I haven't checked the distributor cap or the rotor. Also when my mechanic told me that the plugs were good the car still had the hard start issue. The whole thing started when I gave my mom the car and she put in it some type of gas (I think 89 octane), and it was a generic type of gas. Personally I use only Chevron 92 octane. But do you think something of THAT sort could have caused the problem.
