Ok so I am coming from the experience of working on my old 280Z. I can give that thing a tune up in under 20 minutes easy. Today, was my first time with the 1995 850 turbo wagon. What a pain in the neck. I didn't even have my haynes (cause it hasn't arrived yet). Two hours of figuring it out. I can't believe you have to remove so much crap just to get the cap off. And the rotor. It takes three screws to hold it on. Overkill!! Alright, just ranting. I am so proud though that it is done. My back hurts a bit but it feels gooood. Rotor and cap were a bit burned, and the plugs were a bit white. The only thing easier on this car was the filter as it has snaps and not screws. So I am thinking with the new K&N and plugs, cap, rotor I should see better mileage. Had the oil changed and tranny flushed today too.

Any who, just thought I'd share.

 

Cool also check the wires. The year they were made is stamped on them. If they are original change them as well.

 

Will do. I'll probably be placing another order through IPD soon and will get them anyway. At least they are easy enough to change.

 

Once you do it a couple of more times it will take about 30 min to do it.

 

Yeah, I figure less than 40 minutes for sure since now I know the order in which to remove stuff. I haven't noticed a real improvement yet in the miles per gallon though. Granted it has just been 24 hours. I have done the air cleaner (K&N) the spark plugs (bosch platinum gaped .028) cap, rotor, oil change to synthetic, tranny fluid change, and Chevron fuel injector cleaner. I just had the car to the shop for the firt time since I bought it 2 weeks ago and everything was checked out fine. There are no codes pending or showing and the O2 sensor is less than 10 thousand miles old. I run nothing but shell 91 octane as that is the highest and best gas sold near me. I still have the fuel filter to do and wires too. I should probably replace vacuum hoses although there is no leak and a bunch of them are newish. I keep tires at 36 psi too. My first tank of gas (before tune up) averaged 20.7 mpg. It was 30% highway 70% city (stop and go) So far since last fill up Sunday I have averaged according to the computer 23 mpg with almost 50 50 driving. What is up. I know by reading posts that people are getting better than this. I have a really moderate foot too. It is a bit hilly here but not too bad. The rotor showed some wear, but the plugs that were in it looked great except that they were gapped .040 which I thought was wierd. What else can a guy do?

 

Not to much more to do but finish the tune-up stuff and see then. Also I would clean the throttle body good.

 

Thanks. For the 95 850T is there a write up on cleaning the trottle body?

 

Just for some more info...

I just recently got my T5R and did not think that my mileage was up to par. I was getting about 20 mpg and I mostly drive on the interstate about 75% of the time. I did have a problem with the O2 sensor and once I replaced both heated (to the tune of $600 at my dealer), it has made a world of difference. My power is back and my mileage is up to almost 24. Still not the greatest, but better than it was.

I would be interested to know if anyone is getting better than that? I have been running on 93 Chevron or BP with the octane boost to clean things up a bit every now and then.

 

I run 87 octane and get about 24.5 mpg. I was getting 22.5 before changing my front O2 sensor.

Cleaning the TB is fairly simple. Make sure you get a new gasket, take it off and clean it with cleaner made for cleaning the throttle body. I got my cleaner at NAPA and the gasket from the dealer.

 

There is really no write up about cleaning the throttle body. It is pretty easy to get to and clean.
There is a cover that is held on with a T-25 screw and the throttle body is under there.

 

Thanks as always. I will attempt this soon. I am not worried about it since I have read a bunch of old posts. Hell I have done way more on other cars.

Thanks again all. You rock,
Kyle

 

Sorry to jack your thread, but this is kinda relavent. So I need to tune up my 850 and am debating on going with a tune up kit from someone like IPD or just getting the stuff from the local Checkers. I figured I could save a few bucks through checkers, but should I just pop for the "better" stuff from IPD and the like?

 

I would buy the better stuff. In the long run it will be better for you and the car.

I have seen many junk tune up parts installed and then they came to the dealer with running problems and it was the new parts.

 

Bosch Copper Spark Plugs and OEM Volvo everything else (Cap, rotor, wires, etc)
