What ould make a 2004 dodge intrepid shut down while driving down the road and it starts back up right away after I get pulled over and put it in park and start it again

Dodge and Chrysler products have a history of intermittently faulty crankshaft sensors after a period of time. This will cause your issue. It may also not even set a Check Engine code since it comes and then goes away immediately. If you check for engine codes and don't find any, and if this problem persists or becomes more frequent, the crank sensor is a good candidate for replacement. Also, as they act up more and more, you might find that it takes longer for you to be able to start back up and move again - this is another characteristic of the problem. They are usually easy to access and not extremely expensive.

How do I repair error 4480 when burning a dvd

Error Code 4480 and other serious malfunctions can arise when the Windows® operating system becomes overloaded with invalid system references, as well as corrupted and deleted registry files. These problems commonly occur due to a lack of regular PC maintenance. As a computer operating system gets older, errors and crashes start to become more frequent and problematic.

1991 toyota camry transmission up and downshifts fine with shifter, but upshifts at very low speeds all the way to 4th at about 15 MPH. Will not downshift in any gear, even at full throttle. Tranny codes...

I think your vehicle speed sensor has become faulty. It is on the transmission casing. See here p80

Another possibility is the shift solenoids see p15, p86. This was a common problem in Camry autos. The car needs to go up on a hoist and the tranny pan removed for this repair, although the part is inexpensive. For that fault though the O/D light really should blink to tell you a trouble code 63,64,65.

P0320 & P1391 OBD codes displayed, found during emissions testing but there are NO engine or driving problems idicated.

P 0320 = No Crank Reference Signal to PCM. No Crank (shaft position) reference signal detected during engine cranking (starting).
P 1391 =Intermittent Loss of either Camshaft Position Sensor or Crankshaft Position Sensor.
Hav you attemtped the "3-Key-Ons" method to see these codes on your digital Odometer (assuming you have one) Turn the Key from Off to On (not start) three (3) times. On the third (3rd) time leave the Key in the "On" position (not start). Look at your Dogotal Odometer (if so equipped). The Codes, one at a time should appear. The Last Code will be "P donE".
If te engine is performing without problems: disconnect the negative side of the Battery and wait at least 5 to 30 minutes. Reconnect the Battery. Re-preform the 3-Key-On's and see if and Codes are now showing.
If you start having Start or Running problems becoming more and more frequent: consider replacing the Crankshaft Position Sensor. If this sensor "fails" you may not get any fire to anything, as this is the signal that is necessary for the PCM to initiate the Firing Sequence. The PCM will not send a signal to even the Ignition Coil to begin.

Have 2003 325i has started stalling when I press the gas peddle

Most common problems on E46 is fuel pump and vacuum leaks from old hoses. Get a wireless OBD adapter and OBD Fusion code reader app, read the trouble codes and freeze frame data. If your long term fuel trims are high (>10%) then it's running lean and likely vacuum leak.
Fuel pump should be replaced with an OEM Siemens/VDO brand every 100k miles.
