What extra Intrigue maintenance would you do at 100k miles?

[dizzle1]

The Oxygen sensor isn't that hard to replace if your using a box wrench which is wide enough to wrap the O2's and tighten it. I call it the 1st O2's not the cat sensor I can do it in under then minutes because I already replaced it and didn't tighten it hard.

I get about 17-21 city, 21-24mixed, would be 24-27.5 if mostly highway

I recommend NGK Iridium IX sparkplugs but you will have gap them closer inwards not out, Ac delco is NGK lol saw that myself at the auto parts store.

Krivasauto since our cars are Cutlass Supreme replacments this car was a Intrigue back in the day with RWD 442 just like the Chevelle SS. Man why did GM screw up many RWD Midsized sedans with FWD. I would like a 70 Chevelle SS as a project car but with todays Technical advancements.

Hey Krivasauto since you do alot of work on your Intrigues I wonder if the thought of performance bothers you, well I see you made your point, Because if its going to be completely stock im not going to be happy working on it.

Maybe that's why I like Intrigues so much. Wonder what it would be like to take an lx5 and slide it under the hood of a supreme.

Doesn't bother me - I just know that there is no such thing as a free lunch, I like the way they are, and I am called so often to do other things I would hardly work on my cars if I didn't have to. But I am all for other folks like you showing me how. One of these days I am going to lower the silver one, put some 442 style stripes and hood scoops, and some rallye-style wheels. Sigh. Too much want, too little time and money.

i've seen the map and throttle position sensors mentioned on this forum before.

Would any of you touch those? or just leave them till a check engine light turns on?

I would guess they've never been touched on my vehicle at this point. (partly because i don't know where they are :P )

[LittleHoov]

ooh! ooh! I thought of one!


If you havent already, clean the throttle body. I personally pulled mine completely off so I could get to both sides of the throttle plate really well. At the same time I did mine I also lubed up the throttle spring a bit....for me I noticed that my gas pedal stopped sticking, which Ive heard others complain about, and mine has started doing again. Makes it difficult to give light throttle.

what would you use to lube up the spring?

i've got wd-40, marvel mystery oil, lithium spray grease, PB Blaster, etc

[LittleHoov]

I think at the time I used WD-40, which for my environment is probably best, I live in a very dusty environment, so having a big pile of lithium grease, etc, is just asking for problems. WD-40 kinda cleans and lubricates but it doesnt typically stay around for very long.

Im not sure if my sticking pedal was caused by the dirty throttle body or the spring, I did both at the same time and whatever it was fixed it.

Just leave 'em. The SES light usually does a pretty good job of indicating when these parts fail.

[Scrapper]

no wd-40 does not last long. and another thing if you put that junk on your spark plugs thread you will have a hell of a time getting them out if you don't change often. cleaning throttle body is a good start. bosch plugs i have never liked do you have the split fire in it? that will eat gas. i'd go from anything but those like ngk's or ac's or even motorcraft and those are junk also i'd rather use autolite or anything but boch's,or nipodinzo.

It was probably five years ago. Back when i didn't see too many preferences for plugs. At the time I just went with what that particular shop recommended. I think they were BOSCH Platinum+2 (Part # 4305).

looks like it has two electrodes on it http://ecx.images-amazon.com/images/...GL._SS400_.jpg

I'll probably change them sometime in the next year to ACDelcos just to be safe.

When i get this spark plug change done... would you guys recommend changing out the spark plug boots as well?

I've done that also there was a layer of gunk on the back of it so I used a screwdriver that takes bits star bits I believe. Removing it makes cleaning allot easier. But when you put it back makes sure the perimeter is clean and all aligned well if not throttle will stick.

Check your MAF clean it if its dirty use some QTIPS and some electric cleaner or maybe rubbing alcohol but be careful its fragile don’t apply pressure.

Not unless you tear them up pulling them out, or if they are falling apart from age and heat and gunk. But mine were in good shape, and I just cleaned them off:

that's pretty good at least compared to what's posted on the govt fuel economy site... They estimated 17/26 based on the newly revised EPA estimates. The old EPA estimate was 19/28 for the 3.5L.

http://www.fueleconomy.gov/Feg/bymod...Intrigue.shtml

Does anyone know if the 3.29 gear ratio could affect fuel economy?

[sparcx]

Just did a check of my fuel economy and i think i'm averaging close to 28mpg on the highway. Kind of surprised at the results.

Must be a combination of the recent maintenance that I did like the transmission filter, fuel filter, and MAF sensor. I also dumped a can of Marvel Mystery Oil Fuel Injector Cleaner in recently too.

So happy that i've been able to get it back up again.

I bought an upstream oxygen sensor and new AC Delco (NGK) Plugs the other day. Haven't installed them yet. Probably won't replace the Bosch Platinum 2 plugs just yet as it seems like they're running just fine.

I will probably do the O2 sensor sometime soon to see if i can eek out some more gains.

The one thing I did recently that had the most significant change with my intrigue is changing out some of the Power steering Fluid mentioned in another topic.

I did three or four changes out of the reservoir about once a week and it really helped a ton. It's really brought back the steering to feel like it's a new car again. I think it's criminal that GM didn't mention some sort of fluid change every 50k miles or so. Wish i had done long before 100k.

[sparcx]

Would you guys mess with the brake fluid at this point or leave it be?

I recently changed out the fluid in the reservoir but that's it so far. I was considering doing that a few more times rather than mess around with the calipers since i'm pretty much a novice in terms of the brake system.

You need to check the fluid and see what color it is with a white napkin or paper, mine was light green. I changed it yesterday and now its all clear from reservoir to all 4 calipers. Turkey baste what you can out of the reservoir and top it off with new fluid. I started with the closest wheel FL/FR/RL/RR and proceeded till the furthest. Watch the reservoir as you flush out the old fluid don’t let it run dry keep filling it. The fluid will become clearer as you go and check it with a napkin.

Things you will need:
A person to pump the brakes
Gojo, rags, white napkins, latex gloves
32oz Brake Fluid Dot3 or 4/5/5.1
Hydraulic jack
4 jack stands
19mm socket bit
10mm combination wrench
Clear snug hose for bleeder
Container
Turkey baster
A pan to catch brake fluid when you finally bleed it
Torque wrench- lugs 100ftlbs, 118ftlbs center hub nut to be to spec
