The code is for a shifting problem in the transmission.
You may need to have a transmission shop take a look at it.

Cylinder number 5 is misfiring. Check spark plug, spark plug wire and ignition coil for the number 5 cylinder. The number 5 cylinder is the closest to the front of the car on the drivers side. With engine running in dark (at night) take a spray bottle of water and lightly mist spark plug wires and coil and look for arcing. Autozone will test coil for free.

SOURCE: signal bulb on 2003 buick regal

To change front turn signal –
open the hood; look in back of headlight; two white clips; pull straight up, and then whole headlight comes out including turn signal; it is all one unit; remove rubber cover, then you take bulb out of unit. Mechanism that bulb fits in will need to be turned clockwise (looking from the front) and pulled to get it out of the larger unit holding all lights. Be sure and put rubber cover back on before re-inserting the two white clips.

SOURCE: I own a 1996 buick

It's when the security light starts flashing that the infamous "chip" in the key becomes a nightmare to many. Gradually the car begins not cranking anymore or if it cranks it would start and die in a second. Randomly it will do this more and more often until it won't start anymore. VATS, PASSkey and Passlock immobilizer systems are killing cars all over North America, they have a short lifespan and are certainly more effective against owners than thieves. Here is how you save your car
1st trick, Try a spare key that is newer or used less. The pins wear down and so do the keys causing security fail. 2nd trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year. If its shutting down while running, im sorry i have no quick fix... If anything on this page helps you, please remember to comment or give me a thumbs up on the myfixya sight so i can have a better rating to help more people on this. Thanks

Cheap fix: Bypass the chip in your key. Temporary, but effective. Until the TDM (theft deterrent module) in the dash poops out, then you're kinda screwed. I was told that these types of key security systems have a 7-10 year life span. Sucks for us. This link explains the "Key Issue" pretty well.
----- http://vats.likeabigdog.com/


Never worry again fix: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. Took longer to find the thing than it did to fix the problem. They sell a unit for 200 bucks to totally bypass this system FOREVER. life time-money back and all that. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced... Anywhere from 600-1000 bucks. If you do buy this, please purchase it thru this link. The cost is the same, but i get credit for the sale and im trying to earn my money back, as you will be able to do if you buy fron NewRockies and join the free affiliate program. Thanks
----- http://newrockies.ca?ap_id=judd0081 ----- With this fix, you can take that whole Vats, passlock, passkey system out of your car all together. Good info on both sites.

It works for:
Any GM or Isuzu Vehicle with VATS or PASSKey or PASSLock security systems.
If your car has the chip in the key or in the lock cylinder, then you can save it with this Full Bypass.

What does a diagnostic tool mean when saying "bank 1"...

It usually means the catalytic converter is not getting hot enough to function, but could be another issue. The sensor readings between the sensor before and the sensor after the cat are not within spec.
Bank one is the side with cylinder one, or the side with the catalytic converter.

My buick regal 2003 wont excelerate it starts

It may be the throttle position sensor. You should have a check engine light on in your dash. You will need to have someone plug a OBD II reader in and retrieve the code.
You can spend a LOT of money just putting in one part after another.
Please let me know what you find.

My 2003 Buick Regal is running like ****

Per your description, it sounds as though you have a stuck injector. I assume you have a service engine light on. Take the vehicle to your local Auto Zone or Advance Auto Parts and ask them to scan the car for trouble codes, they will scan the vehicle at no charge to you.
Write the codes down and respond back to this post and we can get started.
Let me know.
