Question about 2002 Buick LeSabre

1 Answer

I had my 2002 buick lesabre tuned up last week. A couple times today, it wouldn't start the first time, but started okay. I added gas tonight and when I started, it wouldn't start and the second time, it sort of back fired and now is idling very very rough and there is a whistling sound when it is idling. It only started today.

    I would go along with the vacuum hose since it was tuned up last week. Don't see how timing would change suddenly. I will check for a loose vacuum hose -- THANKS FOR YOUR INPUT.

Ok, sounds like either a vacuum hose is unattached, that could be the whistling and/or the timing has been changed or is not correct.. it IS a timing issue but I think a loose vacuum hose can also affect that depending on where it is... look for a small maybe 3/8" diameter hose that is not attached to anything...

1998 buick lesabre wont start. had a new thermostat installed last week as heater was blowing cold air. mechanic added anti freeze, car was running fine and blowing hot air. today the check engine light...

Sounds like you have water in the oil which means you could have a blown head gasket. Can you tell what got in the oil. Is it antifreeze or gas. If gas you probably have a injector sticking open.

My 97 buick lesabre Limited is not starting prompty if I pump the gas it helps. It also died while driving, there is no check engine light on.

Tune up time! A tank of bad gas can really throw a wrench in things. I would change the fuel filter, plugs, and run some top notch gas in it to help clean things out

Okay, I've replaced my oxygen sensor last week and

if you used a direct fit O2 it should not be giving you the code again unless the wires are touching near the plug, you got a defective sensor.
if you use a universal it may not read properly.

2000 buick lesabre runs rough. It started running rough and the I drove it around for a while and it was okay for several weeks and then started running rough again and staying that way.

First I would change where I buy gas.And perform a tun up,start with the spark plugs,if it runs okay your done if not #2 change your wires.And clean your throttle body with carb cleaner.

1996 Buick Roadmaster rough start sputters and

Check the mass air flow sensor (clean both heated wires with carb cleaner and Q-tip). does not always work...sometimes they are actually bad. Also check map sensor. Check for vacuum leaks at all hoses and fittings. If engine rpm drops sufficiently, engine vacuum will drop which may have caused a/c malfunction (controls work with vacuum signal) so I wouldn't worry about that 'till the run problem is dealt with.

Car wont start once ieng is shut off for 20mins or longer

this sounds like a defective fuel pump, but u will need to have the fuel pressure tested when it acts up to verify this is the issue 100%, the fuel pump is located inside the fuel tank.
