Default New plugs lower high idle?

Hey guys, my idle is a little high in my '97 850 glt. Sometimes it will have its good days idling at around 800, but most of the time its idle is around 900-1000. I read spec is 850. Would new plugs, wires, rotor, distributor make it idle lower? And what kind of plugs would you recomend? I cant figure out if i get the plugs for the 850 turbo or the 850 n/a since it has the low-pressure turbo.
Thanks, weston.

Well it all depends on if you have your AC on or not. I find that the AC puts aditional stress on the engine, thus it has to compensate. My boost guage raises whenver I turn it on.

As for plugs, I just got the E3 Diamond fire's. I'm sure it won't hurt, as it comes with a 5 year 100K mile warranty. Burn them up, get a new set says I. If you don't want those, I would just get some Bosch's.

my a/c doesnt even blow cold so i never use it. The compressor doesnt even kick in. It idles like that without ac on. Ill prolly get some bosch, ive heard good things about them and their a reasonable price. I would get plugs for a turbo engine since i have the low pressure, correct?

FCV sells OEM plugs (bosch) for both turbo and n/a and i found that the part number is same which mens that the plugs are actually same for both engines.
Please correct me if i m wrong.

Thanks, weston.
If it's due for a major tune-up, then yeah, do plugs, wires, etc.

But if your idle is your main concern i would clean out the Idle Air Control (IAC) motor too. It could be gummed up.

I was thinking of buying the tune up kit from fcp. I just got the car a couple months ago, and according to carfax, hasnt been brought in to the dealer for a couple years so it probably wouldnt be a bad idea. However, the timing belt job is going to brake my bank. I keep stressing to my dad how important it is to replace itsince it has 150,000ish(odo. broke), but he is keeps putting it off.

On fcp it has a tune up kit for n/a and for TURBO models. I still cant figure out what parts to get for my l.p turbo. Doesnt the TURBO have a 2.3 with a stiffer suspesion and the l.p turbo glt have a 2.4?

Don't delay timing belt job. That is most important thing to do.

they are european auto specialists. There is no just volvo specialists in my area. The owners are more saab enthusiasts. they both have 5 saabs and have owned many before them. They seem like trustworthy mechanics. When i did my abs module, all i had was a deep welled torx socket which was a b*tch to get the torx bolts off with. I went up to euromotors and he let me borrow a small torx bit for a little bit. he also helped me get my old spring seats off the struts and helped me put on new ones with no charge. here is their web site: http://euromotorsllc.com/. The other place i went to get a quote was NOT a european auto specialist but had a higher quote.

Well Weston.. All I can sya is that if you know to play with tools a bit, then timing belt is not at all a hard job specially when there are very descriptive writeups here to do the job. I did full tune up with stuff from FCP and added timing belt for about $30ish.

Nonsense - The spark plugs that I got for non-turbo were identical to what I got for m turbo one as well. Please check/compare the links below and any information will be appreciated.

yeah the part number is the same for both plugs. I'm just nervous about doing the timing belt. I have only done a few repairs on it like spring seats, abs module, and wheel bearing and it was fairly easy with help from my neighbor. But i never got into anything with the engine yet.

the only thing scary about doing the timing belt is lining up the timing marks. if you do that ur golden.

what i usualy do is line up the timing marks prior to taking off the belt. and then take off the belt and put the new one back on, double check to make sure its all lined back up. and then move on.

really not that bad of a job. and we are always here to help

nonsense - I got same pack for both engines but what i understand now is that they might be selling premium (or higher quality) plugs for turbo even though the functional specs are same for both engines. the 5-piece blister pack is common for both engines.

weston - What I do is in case of any doubts of slipping a teeth or incorrect alignement, I give more then 2 full rotations to the crank by hand after the new belt is on and before I try cranking the engine. This just confirms that everything is aligned and ther is no mechanincal interference.

+1. and if ur still worried because its ur first time doing it (i know i almost shat my self my first time because i was scurd to turn the key haha). rotate it over a few more times to double, tripple, quad check it. (hint: remove a spark plug or two, makes it ALOT easyer )
