How do I properly reset the computer?

I've swapped in a 130 amp alternator (from 95 Mustang GT). While I was doing that, the battery was disconnected and charging outside the truck. I had the doors open, so I'm sure any residual power is gone, and I think the computer will have reset. There are some starting/stopping/distance things when driving to properly re-program, correct?

I know I've read how on somewhere here, but did a search and couldn't find it. I've also looked in my Haynes manual, no luck. Can anyone help me out?

Thanks!

How do I properly reset the computer?

Have a 88 with a 302, usually I just disconnect the Negative battery cable for ten minutes, then put it back on start the truck up and let it idle for another 10min. Make sure your AC is off and do not rev the engine or anything just let it set. I did this a while ago and the truck seemed to run a lot better than it did.

After 10 minutes or so without any power the computer is "reset". This means that is has lost all memory from the variable inputs it monitors. It will relearn your driving style after a couple of days of driving so that it can start to anticipate certian things. You shouldn't have to do anything special, just drive it normally.

How do I properly reset the computer?

yo, a little late, but here is the info from my 96's Owner's Guide:
"OBD II Drive Cycle
The engine must be warmed up and at
operating temperature before proceeding with
the drive modes of the following OBD II Drive
Cycle.
1. Start the engine. Drive or idle (in neutral)
the vehicle for 4 minutes.
2. Idle the vehicle in drive (neutral for manual
transmission) for 40 seconds.
3. Accelerate the vehicle to 45 mph (72 km/h)
at 1/4 to 1/2 throttle for 10 seconds.
4. Drive the vehicle with a steady throttle at
45 mph (72 km/h) for 30 seconds.
5. Idle the vehicle in drive (neutral for manual
transmissions) for 40 seconds.
6. Continue to drive the vehicle in city traffic at
speeds between 25 and 40 mph
(40-64 km/h) for 15 minutes. During the 15
minute drive cycle the following modes must
be achieved:
a. at least 5 stop and idle modes at 10
seconds each
b. acceleration from idles at 1/4 to 1/2
throttle position, and
c. choose 3 different speeds to do 1.5
minute steady state throttle drives.
343
7. Accelerate the vehicle up to between 45 and
60 mph (72-97 km/h). This should take
approximately 5 minutes.
8. Drive vehicle and hold the throttle steady at
the selected speed between 45 and 60 mph
(72-97 km/h) for approximately 5 minutes.
9. Drive the vehicle for 5 minutes at varying
speeds between 45 and 60 mph
(72-97 km/h).
10. Bring the vehicle back to idle. Idle in drive
for 40 seconds.
11. OBD II drive cycle has been completed.
Vehicle can be turned off when convenient.
344..."
