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.

SOURCE: VTEC System Malfunction code P1259

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

2002 acura TL-s engine code p1456

Code P1456: EVAP control system leakage (fuel system).
Probable causes:
1. Wire harness. Check for correct voltage, open, short to ground, short to voltage
2. Control unit software in need of updating
3. Faulty PCM or ECM
4. Vacuum leaks. Damaged hoses or improper routing
5. EVAP system. Check canister, valves, or components. (gas cap excluded because you say you replaced it)

Some or all of the above could be the source of the check engine light problem.

Gear shifting problem

The 1st thing to do is have a test run on the transmission control module to see if any trouble codes are present, next have you ever serviced the transmission, fluid and filter change, should be done at 60,000 miles, on occasion this can cure problems like yours.

2000 acura 3.2tl radio code

I had the same problem recently with a 2000 acura 3.2tl. I found the code on the bottom side of my hood. I read somewhere that it may be on the underside of the fuse box under the hood but it wasn't. There is a label on the underside of the hood just look for the 5 digit code that all the numbers are under 6 and that should be it, thats how mine was at least.
