Has anyone had or have done themselves, changed out the spark plugs.  If so, did you notice an improvement??

How many miles do you have that you're even considering that.  They are good for 100K.  The last car I had which I changed them at 100K showed no noticeable difference so I suspect they're probably good for longer.

The last time I hit 100K in a vehicle was my 2003 Silverado.  I ended up changing the plugs out at 90K as the idle had gotten a little rough, but the new plugs fixed that. 

I agree with mikemu, you shouldn't have to change them out any time soon, as long as you don't have some other condition that has fouled them.

Are you wanting to put in a better plug like for fuel economy or .......

We have 60K on out Acadia, and was contemplating changing out the Spark Plugs.  Our Mileage has taken a hit since Thanksgiving (from 22 mpg on the Interstate to 18 mpg Interstate - same driving style - actually am going slower 75 vs. 72).  I'm not sure if the cold weather and the 10% mandated ethanol in the gas has caused this hit.  I have a hard time leaving in the spark plugs until 100K.  Will there be issues with changing them (stuck in the head, gall the threads)?

Are there better plugs?

Do you change the air filter on any regular basis?  That could be another cause for the drop in mpg's.  Truly, the new plugs do last 100k miles, even longer!  The main problem with changing plugs is access!  Have a lot of Band Aids ready if you DIY!!

Vehicle has 36k and has seen a drop in fuel economy and sluggishness.  Trip to Vegas last week averaged 19.9 mpg with just my wife and I and minimal luggage.  One year ago I averaged 23.4 for the trip.  I have had it in for all necessary maintenance before the warranty ran out.  Reflash tran, mobile one, even had injectors cleaned, replace faulty Bose Nav radio (would not properly play DVD with MP3's), changed out driver's seat track (thanks to forum for info to get that done).  Use K&N air filter, still looks new.  I am looking at Iridium plugs from Denso.

Can't imagine anything wrong with plugs at 36K unless something else is wrong.

You're kidding, right?  Just based that comment on changing plug wires on a '91 Buick.  That was enough of a PITA and there was a bit more room under the hood than the Acadia!

Really - I had a '90 Grand Prix and the rear bank were nearly impossible to get to.

How does the NAV radio and seat track affect fuel economy?  Poke  Just kidding; anyway did you take the trip to Vegas at the same time of the year and did you take the route through the dam or a different route?  Was one trip in the dead of summer when you needed max cabin cooling?

Straight trip on interstate 15, no stops, 325 miles.  One note....check gauges light came on yesterday (the dreaded engine light).  Could be reason.  Will have it checked out Tuesday.

The dreaded check engine light--tells you nothing about a cause and makes people worry until you take it to the dealer or reset the system manually

You can get a cheap code reader for the check engine light.  It attaches to the OBD II port, and will read the codes.  This will at least give you an indication of what sensor is encountering the fault.  I've used this for my older GM car and I have been successful at pin pointing the problem.

It might be an oxygen sensor.  Engine running to rich.  Probably costs $150.00 for dealer to hook up to their diagnostic center for 1/2hr and then told what needs replacement.  If your car is under warranty, should do for nothing if problem is found.   

You could probably go 200K miles before replacing spark plugs, even though book says 100K.  I'm going to do that with my 06 Mustang which has 102K with getting same mpg when new, winter and summer.   I will be keeping an eye on mpg as I always do.  90% hwy miles thus far.

Good luck in finding out why your mpg is suffering and replacing what needs to be replaced.

Oxygen sensor should be covered under the emission warranty which I believe goes to 80K.
