sounds like the fuel pressure regulator but first try new fuel filter and maybe clean spark plugs and reset them

SOURCE: Misfire in two cylinders

Check to see if the two cylinders misfiring are on the same coil pack. If so, change the coil pack in question.

This happened to me on 1997 Cadillac Deville Limousine.

Also, check for a blown head gasket with compression test.

SOURCE: intermitant stalling hard starting replaced ecm,

Hi, first thing, is your check engine light on? if it is, you can check the codes yourself, get a paper clip unfold it so you got 2 straight ends, find your dianostics port where you plug in the scanner, take the paper clip and stick one end into the one on the far right and the other to the one next to it and turn ignition key to on position, check engine should start blinking if not move the last end of paper clip you plug into the next one in port until it does( turning key off each time before you move paper clip end) do this procedure until the light starts to blink. When it blinks count the blinks, for example it will blink one time than a pause than blink twice quick which means 12 and so on. It will start out with a 12 which means the computer is ready to give stored codes. Just write down the codes and either take them to napa, or auto zone, or to a shop you know, and they can tell you what they mean. On a car that old it could be almost anything, parts wear out, but right now what stands out to me by your description i would check the cadalitic converter it might be plugged. Take some advise get someone that knows something about cars or at least works on them on a regulator bases. That way your not playing a gessing game.

SOURCE: i have a 1999 buick century with a 3.1 engine stop

Did you replace the crank sensor that is in the engine block between the engine and transmission? it has two and the one by the pulley hardly ever goes bad.

SOURCE: audia4t quattro-dies at stop signs and hard starting

Your first mistake is thinking that the only thing that can cause a misfire is a coil or spark plug. Misfires can be caused by MANY things, including faulty fuel injectors, injector control circuits, blown head gaskets, vacuum leaks, burned valves, broken valve springs, low compression due to cylinder damage, worn piston rings, damaged or worn camshafts, etc..

I would recommend getting this problem properly diagnosed by a professional. Failure to fix misfire codes promptly can cause severe engine damage and destroy high-dollar parts like oxygen Sensors, catalytic converters, engine blocks and cylinder heads.

My 1993 buick century stalls when i stop at a light or stop sign after i restart it it backfires multiple time before i can gain speed


I have a feeling your fuel pump is on its way out...but start by changing your fuel filter first, should be under $20....ie..not enough fuel getting through..

Stalls when warm , no start when warm


What you need to do is when it stalls out then check to see if your loosing fuel or spark.Check for spark at the spark plugs.don`t just check one.Check all the front 3 a least.If no spark then you probably have a bad ignition module.It is under the coils.Good luck.

Need to check for fault codes. Possibly a faulty sensor causing the fuel system to run rich or lean.

93 buick century -turn signals


The Buick Century uses separate relays for the hazard warning and turn signal functions. The turn signal relay is located on the accelerator pedal bracket, and the 4-way flasher relay is located on the convenience center near the left kick panel. Try switching these two relays with one another to see if your turn signals work instead of your 4-ways.

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,
huuum
You really need a good honest HANDS on diagnoses!
