CHECK FUEL PRESSURE IT SHOULD BE 41 - 47 PSI. IF NOT REPLACE FUEL FILTER.IF NO CHANGE. REPLACE FUEL PUMP.IF FUEL PUMP IS GOOD.YOUR PROBLEM COULD BE A INTAKE LEAK OR SPARK IGNITION PROBLEMS.ALSO USE A SCANNER TO CHECK FOR FAULTY SENSORS OR THEFT DETERENT PROBLEMS.

SOURCE: Buick Regal 3.8 dies while braking

Check to see if you have a lot of dirt in the throttle body. Clean the throttle blades out with brake cleaner or throttle body cleaner. You'll see alot of dirt come out. Keep spraying until it comes out fairly clear and wipe the throttle body out with a rag. If this doesn't do it, you may have a problem with the throttle position sensor (TPS). This sensor controls the idle after the car warms up and keeps it from dying when you brake or sit at idle.

My 99 buick regal cranks over and starts but has trouble running. If you give it gas to help it through the start up it levels out and runs fine. Fuel pump is good, I've changed spark plugs and wires,


sounds like a stuck open EGR valve to me , take it off of a cool engine and spray some carb cleaner around the seat see if any leaks through to the other side. If it does The valve is bad. Also check out your throttle body for carbon and gumming. W/ engine off spray an appropriate carburator
cleaner into the opening and clean throttle plate and bore with a rag until shiney. put all the air cleaner hoses back together and hold throttle to floor momentarily until engine starts, then rev up half way and release throttle twice quickly, now allow engine to idle idle should be stable and smooth. If not then check for other sources of vaccume leaks.

You name it ive done it!!!! I have a 99 regal with the 3800 series 2 and it is running rough either at idle oe driving and every once in awhile it will just die but starts right back !!! any ideas?


I have a 1988 Buick Century and was having trouble diagnosing a similar issue. $70 and an idle air motor (really looks more like a solenoid-driven valve) solved 60% of the problem...still working on the lagging on the high end, but driving it every day. Good luck!

I hav a 99 buick regal with 3.8 series 2 V-6 its is hard to start then dies at idle now its backfiring threw plinum an exhaust it crack the plastic cover that covers the top of motor


First of all i cannot figure out what a plinum is lol but that is ok... what i think may be your problem my friend is your crank sensor OR your fuel pump they both perceive similar things. What i would change first is the crank sensor because they are about 15 dollars at your local parts store.

I have a 1999 buick regal ls dying.


I have a 99 Buick Regal and it too dies out, but only when I use my turn signals. Sometimes, when trying to start the car...the dash lights would flicker and you can hear some sort of electrical ticking sound. As of today, my car will not start (5/24/09) it hadn't turned over since yesterday. After a process of elimination and searching the net, I think I need a new ignition switch. You may need one as well.

Car Dies


My car idled OK but not great and used to die during stops at times. I replaced the spark plugs and wires without a difference. Shortly after the car died with very little power, just enough to limp home. I had a shop fix it so I didn't guess what was wrong. They replaced the Ignition Module and some of the Coil Packs. They had to replace the Spark Plugs I just put in due to fouling. If you are smelling gas you are putting your cat at risk and might have a more expensive problem later. It cost me $500 but it runs better than ever.
