i know if you don't have good air flow to the air breather, you will loose gas mileage...make sure you have a good clean air filter...this would be a good start for you...

We have replaced our 02 sensors twice initally it


Having owned and thoroughly enjoyed an 01 Durango SLT plus for 6 years, congrats on having the "D".

How many miles on your D? Aging O2 sensors can cause mileage to drop. Which engine do you have? The 4.7 or the 5.9?

You will pretty much find that 11-13 mpg in town is the norm, and 17 is normal for hwy cruising. Towing though in either case will have quite an effect.

Is the gmc yukon 8 cyl 4.8L engine too small for size? Are there many known problems w/ this year and engine size?


Starting in the year of 2000 they quit using a V8 and started using a 327 which is still a 8 cyl. They just supposedly get better gas mileage. But no know serious problems.

WHAT PARTS DO I NEED TO TUNE UP MY 2003 GMC YUKON XL


you don have to do much to that gmc as long the coil is good, just replace all 8 spark plugs, air filter and basic oil and filter change; use good brands of oil, such as castro, mobile, shells ect. if your the original owner and have high miles and never have replace thermostat, I would go ahead and have it done, I would not wait until it fail and over heat on you. if you have done lot of pulling with your vehicle and have 75-100k mile, have your transmission flush with new filter, it will give the tanny life last a bit longer.

2001 Isuzu Rodeo 4WD. CHeck Engine light on and


After market spark plugs could be the problem.
Reinstall the old plugs and see if that fixes it.
This vehicle has an ion sensing ignition system and is real sensitive to the proper spark plugs. I would get the proper plugs from the dealer if the old ones work.
The codes P1311 and P1312 are ion sensing codes.

2004 Dodge Intrepid Check Engine Light & Bad Fuel Mileage


If it has never had plugs changed, i would suggest it. It can make a big difference.

Labor time is .8 hrs + 6 plugs = $80 - $150.

Take your car to a parts place and they will usually check and clear your light for free.

Firestone likes to up-sell everything, $650 is way too much for a basic tune up.

My GMC yukon XL 2001 engine runs after 4 times of cranking.


Try turning key to on only, not start, 2 or 3 times first then try to start. If it starts good first try, then I'd change my fuel filter & then have fuel pressure tested if fuel filter didn't help. You may be looking at a new pump, but lets do filter & test fuel pressure first.
