Top 10 1999 Buick Regal Questions & Answers

Maybe a solution.  Are you sure that its because your using your turn signal?  Does this occur while moving or while sitting idle?

My car engine would turn off while sitting idle at a traffic light.  Many people turn their signals on while idle instead of before they get to the light or stop sign.  There is a problem with the engine getting too hot while stopped and then turning off.  Make sure you're put your signal on before stopping and see if that makes a difference.  If it keeps turning off while just sitting it may be the engine.  

However this might be something different and if so that very weird. 

its the button on the shifter, sometimes it doesnt contact the key unlock solenoid. all you have to do is turn the key to on position, (not start) press brake, and push the button on the shifter, youll hear a click in the ignition. then key will come out

This is a chronic problem on the LCD display for Buick Century/Regal cars with the climate control HVAC system. The problem is most often some of the resistors on the PCB will get a "cold solder" joint and need to be fixed by remelting the solder and adding a bit more fresh solder. Remove the unit from your dash and inspect all the solder joints. Chances are you'll see one of them that is "loose."

3.8L Engine

NOTE The 3.8L (VIN K) non-supercharged engine uses a two-piece intake manifold consisting of an upper air plenum which mounts the throttle body and a lower intake manifold assembly which houses the fuel injectors. The 3.8L (VIN 1) supercharged engine uses a similar lower intake manifold. The supercharger serves as the upper manifold.
Lower Manifold

NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold. Remove the upper intake manifold to service the lower intake.
The 3.8L (VIN 1) supercharged engine uses a manifold similar to the 3.8L (VIN K), but the supercharger serves as the upper manifold.

1. Disconnect the negative battery cable.
2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
3. Remove the upper intake manifold using the procedure above.
4. Remove the EGR outlet pipe from the intake manifold.
5. Detach the engine coolant temperature sensor wiring harness from the sensor.
6. Remove the lower intake manifold bolts and carefully lift off the manifold.

1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces and between the lower manifold and the cylinder heads..
2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Apply thread-locking compound to the bolt threads. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 11 ft. lbs. (15 Nm). Follow the toque sequence, starting in the center, then working outwards in a circle.
3. Install the remaining components in the reverse order of the removal process.

1. Disconnect the negative battery cable.
2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
3. Tag for identification, then remove the right side spark plug wires.
4. Disconnect the ignition wires from the fuel rail.
5. Remove the fuel rail. Please see Section 5.
6. Remove the cable bracket from the intake manifold.
7. Remove the throttle body.

1. Remove the upper intake manifold bolts and carefully lift the upper intake manifold from the engine.

1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces.
2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 89 inch lbs. (10 Nm). Follow the torque sequence, starting in the center, then working outwards in a circle.
3. Install the remaining components in the reverse order of the removal process.

The only way that the ABS light could have anything to do with your stalling problem is if it is caused by a bad battery ground, Otherwise, I would begin diagnosis by collecting fault codes from both the ABS module and the Engine Control Module.

Hi and welcome to FixYa. I am Kelly. If you have your owner's manual there is a picture on page ;6-29 of your power steering fluid reservoir. If you do not have your owners manual download this manual:
http://www.extendedgmwarranty.com/owners-manual/buick/1999-Buick-Regal.pdf and go to page 269 to see the picture. It will be in front of the engine driven by a belt on the left front side closer to the fender well and radiator. (Left front corner of the engine) NOTE the full mark on the dip stick.

On another note... with the car NOT RUNNING.... place a finger on the power steering drive belt mid-span between the drive pulleys and check for deflection. If it mores more than 1 inch as you gently depress the belt.;.. then the belt is loose and it will need re-tensioned. Most of the time this is the cause of the noise your hearing.

Thanks for using FixYa,

Kelly

P0422 Buick - Catalyst below threshold.

Catalytic converter is clogged or out of medium.

Replace it.


ACTUAL DIAGNOSTIC:

Fault Code Definition
Code P0422 indicates that the Bank 1 Main Catalytic Converter's emissions efficiency has fallen below the minimum allowable limit. This threshold is tracked by a Catalyst Monitoring Oxygen Sensor located on or near the outlet of the Catalytic Converter.

Symptoms

* Check Engine Light will illuminate
* In many cases, no abnormal symptoms may be noticed

Common Problems That Trigger the P0422 Code

* Defective Catalytic Converter
* Engine misfires have damaged the Catalytic Converter
* Internal engine damage resulting in high oil consumption and/or a leaking Head gasket has damaged the Catalytic Converter

Common Misdiagnoses

* Oxygen Sensors are replaced when the real problem is a damaged Catalyst
* Catalyst is replaced when the real problem is internal engine damage, which is producing elevated emissions levels
* Catalyst is replaced when a misfiring engine is the real problem

It's that infamous "chip" in the key that becomes a nightmare to many. The security light may or may not start flashing. Sometimes it stays on steady. Gradually the car begins not cranking anymore or if it cranks it will 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
QUICK FIX TRICKS
1st trick, Try a spare key that is newer or used less. The pins wear down with use and so do the keys causing the security to 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, I'm sorry I have no quick fix...
CHEAP FIX: Bypass the chip in your key. This is 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/

If you're gonna tear your car apart anyway, just do this next fix and bypass it all together. Its more money, less work, and a PERMANENT fix. Up to you tho.

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. It took longer to find the solution 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... It can cost anywhere from 600-1000 bucks. If you do buy this, please purchase it thru this link.
----- 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.
It works for, but is not limited to:

Hello
Most of time the service vehicle soon light is on is because a bulb of some sort is out headlight, foglight, taillight or brakelight replaced whatever bulb is out and the light should reset itself
Good luck
Chris

disconnect battery. then turn on the ignition to drain the memory.turn back off .then reconnect the battery..
