The pcv valve may be located below the MAP sensor but the electrical connector & the MAP sensor seem stuck. I do not want to break them. Should I force it? Am I in the right place for a 2001 buick lasabre? How do I replace the pvc valve?
Thank you,

My car had been lagging for quite some time almost like there was a problem with the airflow. One day it starting bogging out more than normal, so my girlfriend hit the gas to get it to go. When she did this you could feel it was too much at once and took it a second before it actually caught the right airflow or whatever then it finally got the power it needed and took off down the road. It was fine until we got maybe another 1/2 mile to 1mile if even that far, and we heard a loud noise( kind of like a a lot of built up air pressure being released all at once). Immediately the car exhaust was so loud like I've never heard before. When I looked under the hood, where the exhaust pipe connects to the back of the motor looks like the pipe is not connected on there like it's supposed to be. It's the long pipe that runs up to the motor and connects to the accordion looking pipe. Neither of them are hanging on the ground, the 1 is still sitting in the other it's just resting on it. This is the best I can describe it. I hope this is enuff info for someone to help..???!

On my way to work this morning and car started overheating and smoking. I checked under the hood and the lower hose was dis attached. I attached it back on the radiator, still overheating. On my break today i put on a new thermostat and its still overheating. What are some other options that will at least get me home today. I home is about 40 miles from my job.

AC blows cold air, flow is mostly in the floorboard, even thought the control is set on "mid". Very little air comes out the vents.

The Gas Cap Loose Light will only come on if the gas tank is below 3/4 full and and above 1/4 full... If you fill up your tank... and use an EMC Scanner to reset the code... You could also get a Battery Disconnect switch as well... Scanner cost $65 at Autozone... You can order a Battery Disconnect switch on Ebay for like $7 .. once your codes are reset and cleared... you can ride for like 90 miles before your gas tank goes below the 3/4 mark and the Gas Cap Loose Light would go on.. if you fill your tank before the light goes on say at like after 85 miles... you would never have the light go on again... I am retired and I don't mind filling up 3 times instead of 1 times ... I have air shocks and I make sure they are pumped up when I am at the gas station as well. I may gas up two times a week. I also have an extension for the seat belt... so I can keep it off and not wait 1 min for the "Fasten your seat Belt Light to Go Out"... and I also put a locking Gas Cap on my Buick Lesabre... because a locking gas cap is better than to let anyone put something into your tank anytime that they feel like... For example anyone could just open the door and unscrew the cap... put a rag in the gas tank hole and light the rag... if you get my point.

When heat is on the blower works well, but after warming up, the air coming out is luke warm or cold. Engine temperature around 180 degrees. Seems as engine gets warmer, air coming out of heater gets cooler

Battery replaced but the LeSabre will not start the next morning unless jumped. Nothing is left on. Alternator is working so i know it is charging when running.

just bought a new radiator becouse i found a leak in it and it has been trying to run hot.now i noticed the elbow pipe has a leak, how do i go about replacing it...

My Son was putting gas in his 01 LeSabre custom and gas started pouring out underneath the car for a few seconds and stopped. Anybody know why this would happen?
Thanks!!

2001 Buick LeSabre Limited car shut off while driving - turned the corner and it cut off. Cranks but wont start. change fuel pump/ and crank sensor. Still wont start/ now the right signal light will come on and flash when turning on the key but signal light is not on also right headlight will not work. could it be something in the steering column?

My 01 Buick lesabre has a rattling noise coming from underneath it. I had the tranny fluid and filter changed what could be the cause of the rattling sound?

No heat. Replaced cabin air filter.

The cruise control switch will come out easily & snaps back in on the stearing wheel. Can I do this without disturbing the air bag?
I am getting yes & no answers. Which is correct? The car has 135000 miles on it.Automatic 3.8.

How do I fix the cruise control light?It does not effect driving the car.The problem started yesterday. I never use cruise control. The only time it is on is when I touch
the button by mistake while driving.
Thank you,

doesnt seem to be enough room to turn counterclockwise or lower to drop
