I would first try and reset the Powertrain Control Module since you replaced the alternator. This will clear all the codes and turn off the check engine light. To do this, pull the No. 13 "clock backup" fuse from the passenger kick panel fuse box for 10 seconds then replace.
Now, you should also do the Honda "idle learn procedure". This lets the computer calculate what a no load idle condition is so it can adjust idle speed when the engine or alternator is put under various loads. To do this, make sure all electrical items are turned off. Start the engine and hold it at 3,000 rpm in park or neutral until the radiator fan comes on or until normal operating temp is reached (about 4 minutes). Now let the engine idle for a minimum of 5 minutes with no loads. If the radiator fan comes on during the 5 minutes, the amount of time it runs must be added to the 5 minute period--the goal being a period of at least 5 minutes without any loads on the engine or alternator.
Also check the vacuum line to the evap solenoid. It is on the top of the engine near the intake throttle body.

Testimonial: "Thank You for your response. Very Helpful in resolving my issue."
P1259 Immobilizer to PCM Signal Error,, ok, first does the car hic up at around 4000 rpm'? what you have here is possibly 2 things with a honda, and that code just happens to pop up for both,, One, change the oil, and 2, you may need to change the Vtec pressure sensor/screen (solenoid),, its located between the Vtec solenoid and the head,, My guess is that your oil is pretty bad, or you just had an oil change, either way ,, clean that sensor,, it may or may not work, if not, you'll have to replace it
