>His explain that this is common in 2001 buick.
If he claimed that Upper Intake Manifold seeping or leaks area common in 2001 3800s, run don't walk to a real mechanic who's not trying to sell something.
The recall involving UIM was actually the throttle body where it is pressed onto the end of the UIM by 4 bolts/screws and they replaced those with larger washers under the screw to spread the pressure out more and they changed the gasket around the contact and they put antileak pellets that have ground up pepper or walnut shells or something organic into the coolant.
The hot coolant comes up through the UIM and goes into the throttle body assembly to heat it for better performance quickly when the car is started. Apparently because they quit putting sealant into the motors at the factory, a few gaskets had seeped. That's an exterior seep in most cases. And it was rare.
The UIM leaks on the prior version of the manifolds up to 99 were caused by seeps around the UIM gasket to the outside or from the part next to the EGR internal HOT tube deteriorates the plastic and allows seepage from the coolant passages to the throttle body.

Right now we are using gas with ethanol in it.
85 Octane 18mpg City, 29 Hwy (Foothills) 31 (Flat) Car does NOT like this gas, it runs really rough on cold mornings with this fuel.
88 Octane 21mpg City, 31 Hwy (Foothills) 34(Flat). Car runs much smoother with this octane gas, and cold morning starts aren't as harsh.

Any pointers on replacing these before I begin? I just purchased this car and it's in very nice condition but I can hear and feel the rear shoes. They don't sound like metal to metal yet so I figure I can get by this time with just pads.

We live in North Jersey and travel to Raleigh, NC regularly, a distance of 512 miles to visit our oldest daughter. Our 95 Le Sabre just turned over 100K miles and consistantly gets 34 mpg on this trip. Unless we get hung up in traffic around Washington DC. I thought my car was the only one that did so well but now I see others who are also fortunate. Why did they have to change things.

I have a 92 Lesabre with the 3800 series (before the series II with the coolant problem), with 155k+ mi on the odometer.
I get at least 20mpg around town, and 28 - 30 mpg highway. (30mpg was the most ever doing 75mph on I-84 between Pendleton, OR and Portland, OR.) Who says you have to have a brand new subcompact to get decent gas mileage?
Oh, and with a tranny cooler and brake controller I can tow 3000 lbs, too.
Maintenance is pretty much just oil changes, tranny fluid changes and brakes.
I had to replace the driver side seat belt latch and the power antenna recently. Both were cheap at a u-pull-it. My A/C compressor went out last year, but with the help of a local A/C tech I am able to fix the A/C and convert it to R134a for less than $200.

can i run premium gas in my engine without it causing any trouble, I'm guessing i can cause all the octane rating is, is resistance to pre ignition so i dont think it should damage it

Hi folks new to the board,
I don't drive fast, or crazy and I only get 20mpg on a 17 mile commute to work (one way). I am not pleased at all with 20mpg, and got 19 on my previous tank.
Car only has 58k, new a new air filter and tires are ok. I know it takes a couple miles for the engine to warm up in 9 or even 25 degree weather. The OD takes a couple miles to shift into OD just like my 01 Taurus did - that happens on cars.
Does anybody else have this problem in the winter? Please advise!

What kind of road conditions (wet, icy, snow packed, dry)? What kind of traffic (stop and go, slow and go, or just go)? Does your state add ethanol to the gas during the colder months? What do you consider "not crazy" or "fast"?

Is this a commute with stoplights every quarter mile and stop and go traffic? Or is it a commute with 45 mph on the expressway.
In short trip driving of a couple miles on errands with few stoplights our car tends toward 22 -24.5 mpg. We drive gently. The car is parked in a warm garage for cold starting.
If your car is outside at 10 degrees, it takes a long time for the transmission to warm up. I can see the mileage go up on our car for the first 10 miles on a cold day when I get on the interstate for a longer drive.
Try a different brand of gasoline to try to minimize the alcohol you're buying.
And different tires have different rolling resistance. Keep them 2-3 pounds above the recommended which is probably 30 psi. Remember to recheck them after the temps drop; tires at 50 deg. have 4 more psi than tires at 10 degrees. Check the tires cold.
If your commute is like the first I described, you may be doing okay.
