This happens a lot to this model. Check the EGR system! Fuel pump and injector cleaners may help. EGR system is probably it.

I have a 2001 isuzu rodeo and my gas needle is broke, how much would it usually cost to get fixed, how many highway miles per gallon and city miles per gallon please?


You would need to check with a local garage for repair prices.
To find your average mileage, fill up the tank, write down the mileage, then do it again at around 200 miles. Divide the mileage traveled by the number of gallons used. I would recommend filling up after you have used about 8 or 9 gallons to prevent running out of gas. You can't go by the federal mpg numbers because everybody drives differently.

What is the fuel economy for a 2001 hyundai santa fe ? is it normal to go throu gh half a tank of petrol in 3 to 4 days ?


Average for a V6 engine 2 wheel drive model is 20mpg. That is 20 miles per gallon US.
If you have an 18 gallon tank, you could expect 180 miles on a half tank of fuel. Again, this is US measurements.

I have a FORD Econolinen 1993. When I drive he abuse 45 ltres of gaz on 100 miles . Is this normale ?


on normal that trk should be around 6-7 gallons used per one hundred miles drove. i based that at 15 mpg. now that is also based on a V8 engine. now 1 gallon of gas is 3.78541178 liters which totals 12 galons of gas to 45.42494136 liters. This would mean that it took 12 gallons of gas to travel 100 miles which totals 8.3333333333 mpg. not as good as i would have thought. 8 miles per gallon (mpg) hell that engine must be a big block 460. If it is that big cubic inch i could understand but any other motor should do better mpg than 8.3. so i agree that is not normal, tune up, or look for fuel leak in the fuel supply or( feed ) line. From the tank to the motor. This must be a canadian truck yes? well hope for the best or trade that guzzler in for a new breed. stay warm!

When should i change the oil in a 01 buick century


Same as on all your vehicles
When ever you like

I would suggest 3 to 4 times a year
depending on how many miles you go

Average--about 3,000 to 4,500 miles
between changes

I would use 5W-30 Full Syn,any brand

Mobil one does a good job of keeping
the oil pan at least clean,I have pulled a couple
It is at Wal Mart

Im only getting 10 miles to the gallon on my '92 buick century, although i'm not leaking anything


I would suggest checking the catlalytic converter. It could be plugged really bad. This could be the culprit to your poor gas mileage. Hope this helps!!

1992 buick century(26,500 original miles)engine shuts down but starts up, no problem Any ideas as to what might be causing this?


As this vehicle is obviously driven around 1,500 miles per year, you may have moisture in the tank from it sitting for long periods of time with a half empty tank of fuel. Start by changing the fuel filter. Purchase a can of Seafoam Motor Tune and pour 1 can in a full tank of fuel. This is an excellent fuel stabilizer, moisture remover, and fuel system cleaner. After one tank of fuel if you see no improvement then look for another problem.

Instrument Cluster Panel out on 2001 buick century


2001 Century just hit 40,000 miles and the engine light has come on. Im wondering if this is an automatic when the car trips at 40K- for a check up or whatever GM wants your money for.

ps - from '89 to 2008 I had been driving Nissans, Toyotas and Hondas - Im driving this car only because I gave my Toyata Rav4 to my daughter and got this Buick from my elderly mother as she no longer drives. Its is amazing what a piece of **** this car is compared to what Im use to. At 40,000 miles you start having the engine light come on - amazing!

1992 buick century..


Your O2 sensor(s) are fouled. This could be an expensive repair ($200) or inexpensive. Try adding "SeaFoam" ($9) available at Advance Auto Parts and WalMart add to your tank per instructions on the can...(cept you have to drive the car at least 100 miles thereafter).
Good Luck
