how often? 30k? 60k?

IMO, 60K. But following the manual is a good idea too.

It depends on what you mean by tune ups. The term "Tune up" doesn't really apply anymore to modern days cars and replaced by maintenance schedules.

just the typical...clean or replace spark plugs, air filter, replace distributor/rotor (and if needed...spark plug wires, PCV valve, fuel filter, and O2 sensor)

thought 60k seems more practical...factory G6 comes equipped with platinum spark plugs, yes?

All those items have different replacement intervals.
Distributor, rotor, fuel filter no longer need to be replaced.

I'm thinking the manual and what seems most sane is replacing the spark plugs and wires (if needed) at 100k unless you are having power problems. Air filter should be around every 10k miles or so, usually the oil change places pull it out for you to look at and if it's clogged probably a good idea to replace it.

I had a 2001 Lumina that got "tune up" after about 100K miles before I traded in for the G6 that cost $600+ to replace the spark plugs/wires and PCV valve. I agree with mrslcom with saying I don't think the rest needs to be replaced.

This is a good topic, we can have several different driving habits and/or conditions. If you putt-putt around town or drive hard can be the factor in getting a tune-up. I used to work at a location that required me to drive on a gravel road for about a mile, behind other drivers. DUST was everywhere so changing the air filter was a regular thing. I just changed out a set of plugs on another car I drive (Mazda 6S) daily. I put 134000 on the original set of plugs but I drive 98% interstate with the Mazda so I feel the plugs will last longer than the G6 which is a daily driver for my wife. Being old school with automotive repair and modifications I rely on the performance of the car to determan if it needs a "tune-up" or just a set of plugs.
Back when, a tune-up involved spark plugs, points, rotor, distributor cap, spark plug wires, air filter, fuel filter and a timing check to name some of the items I changed out.

that's good to know that there are fewer things done for regular maintenance...it significantly reduces the cost of car ownership (according to statistics, the 2007 G6 has a below average value rating. though, the '08 values are average and the '09 will surely do as well)

50k-rotate tires,lof,tranny flush,air filter, check brakes and suspension
100k-same as above,spark plugs

How much does a tune up cost?
"just the typical...clean or replace spark plugs, air filter, replace distributor/rotor (and if needed...spark plug wires, PCV valve, fuel filter, and O2 sensor)"

Anyone know what price range?

I plan on having the tranny fluid drained @ 75k, if I remember correctly it should be changed @ 100k.

At 100k I'll do the serpentine belt, wires, cap, rotor & plugs & flush the cool system.

i've got a 2005 g6 gt and i wanted to swap out the spark plugs for these bosh fusion plugs i just got. at first glance i figured that they go in near the top of the engine where 6 wires are plugged into this black base but i removed the wires and the spark plugs are to big to fit in there so i took the black base off to see if they go in underneath but its a no go, any ideas?

they sould go into the side of the engine on the other end of those wires, make sure you mark which wire went where on that black base.

mabey you should let a shop put in your spark plugs if you dont even know where the spark plugs are located :eek:

i swear some people do not need to mess with cars lol :bash:

Correct me if I am wrong but there is no dist. cap or rotor on these car.

Tune up should consist of fuel filter, plugs, wires.

plugs and wires....cant do the fuel filter (it's in tank)

Oh that sucks! What a crappy design hope I never have to replace that!

I think you are right, is it coil packs?

Yes, that would be the black block bolted to the intake manifold near the fire wall.

IMO i would't bother replaceing that unless it actually goes out on you. i did the plugs not too long ago at around 78k miles and am goin to put in some new MSD super conductor plug wires soon when my tax return is deposited. im at 80k currently.

i also pulled off the throttle body and cleaned it too, i think i saw on another site where someone where someone put a catch can for oil in the PCV line for their GTO is there such a thing for the G6? i recently had the intake off an found quite a bit of oil inside the intake an throttle body already again.

Fuel filter shouldn't require replacement. If anything the pump and sending unit will fail before the fuel filter clogs. Unless of course, you fuel your car with open gas cans that sit outside, then you'll have problems.

As for tune up, I change the oil once a year (Amsoil 0W30), check the air filter every four months, or seasonally (Amsoil high flow drop-in). The OEM plugs can go up to 100K, but I'd never leave any plug in that long, as you'd be asking to have a plug seize up in the head. Replace every 50K or less. After these OEM plugs are ready to go, I'll put in copper core plugs like I use in all my engines. I change them every 40,000kms, or 25K. They still look like they can give me another 25K, but for less than $2ea, it's a good investment to change them out.

One thing that is overlooked, even by some oil change places (if they do this), is to check the exterior lights and make sure they ALL work - brake lights too!

Changed plugs. 3.9L HO.

Installed E3's. Noticed quicker throttle response.

FYI...If you have this engine you will need to remove the alternator to remove and install the back plugs. No need to disconnect wires from alternator, just release belt and take blots from alternator and move it out of the way.

Took about 2 hours.

Thanks for the Tip JetMech I have 83,000 on my 06 3.9 GTP and really need to change them out soon! Did you do the wires too? I was thinking of putting back in the acdelco iridiums and putting on better wires but have not seen that many options.

hey Cal you might want to look into kingsborne. http://www.kingsbornewires.com/main.sc

FYI

Dash hawk picked up a lean condition bank 2 after E3 plug installation.

Not sure if its the plugs or something else. Did not have a DIC warning or check engine light.

Will check intake for vacuum leaks.

O2 #1 and #2 voltage seems normal and close to the same....

I figure its the plugs. Will drive it for a bit and see if it corrects it self if no other issues are found.

Keep you posted.
