Question about 1994 Buick Century

Open Question

1994 Buick Century stalling out.

On Sunday my 1994 Buick Century began stalling intermittently. It seems to happen when going into a turn or slowing to a stop. Generally it will start right back up- today it started, and died when I put it into gear three times before I could get it to go. Also- if I keep giving it gas while braking- it doesn't stall. 2 other pieces of info that I dont' know if they make a difference. First- We just had to replace the water pump because it was overheating and not holding antifreeze- the stalling started after the first time it overheated on Sunday. Second, when I was driving home after today's stalls- the gas needle kept rapidly bouncing between between 1/2 and 1/4. Thanks for any help you can give me.

SOURCE: My 1991 buick century keep stalling out but starts

You need to test for spark at the spark plugs with a spark tester that can be purchased at any auto store. Then if you have spark, spray ether into the air intake to see if will start...if that doesn't work. Let us know where you have spark or not and did the ether make an attempt to start.

SOURCE: transmission ?

The TCC solonoid is bad I have changed hundred of these there is a square coector of the front side of the transmission, this is the connector for the TCC ( torque converter Clutch) it has a tab lock put your finger nale under the tab or a smal screwdriver and lift gently and pull the connector off the car will now drive when you put it in gear but NOT have 4th gear and theck engine light may come on you should get this fixed as soon as possible you have to take off the side transmission cover the TCC is in there only buy one directly from the GM dealer no one else trust me on this, and also change te transmissin filter and gasket while your there.

SOURCE: stalls out

lisalavin,

You said,

My 1990 Buick century stalls out when in park after idling for a minute or two and stalls out when brake is applied. last night it did this every time I had to stop or make a slow turn it also started shaking a bit but if i released gas a little bit it would stop. i thought the shaking might be the cvu joint as it needs to be replaced but it started doing it on straight aways and hills also but would still stop shaking if gas was eased up on. Closer to home when it was stalling the only way I could get it to stay running while I put it in drive was to have one foot on the brake and the other on the gas. Is this a matter of changing the fuel filter or is it something more complicated?

It can be one of many things causing this!
1. Low idle, needs to be raised
2. A vacuum leak, needs to be diagnosed.
3 The choke, if it's when it's cold or the engine is cold and not up to running temp.

4.But, I'll l bet it's a idle sensor

Or last and probably NOT a broken baffle in the cat converter!
this usually happens more often not just with the stop but even when driving!

Bless you,

Check the EGR valve. Sounds like the three stage EGR valve is acting up. Look for any discoloration around the valve ports. This valve is located on the intake manifold near the throttle body.

SOURCE: car turns off while driving, and now it wont start

It maybe a bad crank angle sensor or a bad throtle position sensor.

96 Buick Century stalls....


I spent endless time on this same problem on my 1992 Wagon. I changed out the computer but no help. It turned out to be the top dead center crank sensor that tells the system when the crank passes TDC. It is a small magnet essentially about the siz of a pencil eraser in the flywheel. it was cracked and occasionally would not "sense" and the car would just quit. troubleshooting was a nightmare because the computer diagnostics on the 1992 are less capable than the 1996 model. Anyway that is a relatively inexpensive fix and easy to know if it worked. Let me know how you solve this.
