This can be caused from a drity throtlebody or bad idle air control valve, start by making sure the throtle is clean then have the idle air valve checked, when starting the valve should open to raise idle and drop down after it starts, it sounds like your doing what the valve should be doing, hope this helps.

Try disconnecting the MAF sensor and see if it dies then. If not you can attempt to clean the MAF sensor or replace it.

1998 Buick century hard to start when warm


Although this is almost impossible to diagnose without access to the vehicle, it is quite common for the Mass Airflow Sensor to get dirty and cause this kind of issue. I would remove it and clean it. Cleaners are available at almost any automotive parts retailers.

You have a fuel starvation problem, fuel pump, pressure regulator, injectors, any or all of them could be the reason why you are not getting fuel. Someone is going to have to lay hands and eyes on the thing and check it out.

Ive been trying to start my buick century, it cranks strong, but it seems like its not getting gas, its been sitting for about 3 years.. i nee help as quick as possible... help please thanks!


I would say your gas is bad. Three years is way to long for sitting gas. You will need to drain the tank. Spray some gas into the carberator. Start it and see if it catches for a second. If so, then that confirms a fuel problem. The gas is not good my friend. Sorry.

When was the last time the fuel filter was replaced? you may have a fuel filter that is getting restricted or possible the fuel pump is going bad. You will need to check the fuel pump pressure, and see if you can blow through the fuel filter. Hope this helps.

Maybe you picked up some junk at the bottom of tank. Check your filters and good flow to throttle body.

Starting car if doesnt catch the first time


if it's fuel injected you will cause yourself major headaches by giving it gas (flooding) so you should actually be able to start the car without touching the gas pedal
