Hey fellas,

I have a 2nd gen myself and i work on that peice just fine, but i get on my freinds GSL-SE in bone stock form and its a little different. At anyrate, i can get the idle down to say 800 and its fine, but then when you rev it, it goes back up to 2K. Ok.. odd... i adjust it back to 800 rev it... goes to 2K again. Now i have run out of adjustment room (screws are maxed out) and its nice at 2K. Is there an idle set jumper on these cars? i didnt see one, i know there is one for the 2nd gen, but i looked and didnt see one on this car. Thanks guys.

 

Try adjusting or removing the valve that slows down the deceleration. It's on the left next to the throttlebody looking in from the passender side.

 

Check the flapper door in the AFM and make sure it isn't getting stuck..are the any vacuum leaks?

 

I adjusted that dashpot on the left, thanks, to no avail.

There doesnt seem to be any vacume leaks, i replaced all the vacume hoses with new ones and all gaskets look great. Its really got me stumped here fellas.

Ill check the AFM tomarrow, though i doubt that would be the problem.

It seems more of like an ECU is re setting the idle because ill adjust the screw(s) (im using all the idle set screws, not just the one at the top of the TB) to get it to around 900 or so and then ill rev it, or restart the car, and its back to 2K. Is there an initial set jumper for the idle one these cars? Thanks.

 

Sounds like you need the "David Lane" complete write up on adjusting idle on the GSL-SE. Anyone got it bookmarked???? C'mon someone has to have it somewhere... I know I should have it also.. but I printed myself a hardcopy to read while ACTUALLY adjusting the idle.

 

might not be an adjustment at all - sounds more like one of the solenoids is sticking

 

What solenoid would cause that? I was looking and the GSL-SE has four soliniods, two are round looking and two are conventional type that we have on the 2nd gens. Tomarrow ill mess around and see what i can do about the idle/solinoids. Ill run a search on the "david lane" deal. Thanks again fellas.

 

Is the CRUISE CONTROL SOLENOID still connected??? IT'LL cause it to get stuck above 800... but I don't know if it gets it stuck at 2k... but try removing that cable on the trottle body...

 

make sure the variable resistor is set right and the TPS is right... and make sure the trottle body isn't gettin stuck... old springs = friction.. not enabling it to go back down... ALSO check the DOUBLE trottle diaphram.. see if the lever is easy to move... make sure a vacuum hose that connects to the BAC valve is connected

 

Will do, although i did check the tension of the cables to make sure they werent restricting it, i didnt, however, check to see if the cruise control cable was kinking up after the idle goes up to 2K, that may be it, i think you guys are narrowing it down for sure. Does anyone have a manual or write-up on line about these things? Like a diagram of the solinoid rails and things like that? i have one for my 2nd gen but it doesnt seem to help that much. If not, if someone could just tell me what the four soliniods do. Thanks

 

I set the TPS today right, i didnt see a place where the variable resistor was, is it caped off? the springs feel good and so does the throttle body itself, the car is in prestine condition. All vacume lines are where they should.

Anyone have a vacumeline/soliniod diagram? or an electrical diagram period for this car? Thanks again

I think this should help you

 

looking at this again... I just realized that I have a vacuum switch up with the switching solenoid and the relief solenoid.... gotta go switch it tomorrow...

 

oh man you're a ******* life saver MRGSL-SE. Man, you know, kinda off subject but while we are talking about GSL-SEs why not. I have a 2nd gen that im breaking the bank and tears on and its pretty quick rides good runs great. But damn if one ride in the GSL-SE make me want to sell it and build one of these up. The damn handling is incrediable, like rails and **** if they arnt nicer built cars it seems. Anywho, mad compliments to anyone with a GSL-SE and let me know if there is one for sale. Thanks again guys

 

Cleaning the TB and checking all vacuum hoses is a must.

As for your 2nd gen..that's because you have an NA. I'd take a GSL-SE over an S5 NA anyday.

Well i looked at it today, and i had a few vac lines im the wrong place, put them where they belong and it was running alot better, less jumpy, but the idle was still sticking. I think it is from the BAC, i had the idle rock solid at 800 and i reved on it, the idle went up to 1500 and hung there, so i got the screwdriver and beat the BAC in the middle and the idle went back down, i th ink its sticking so we slaped it in a bit of lacor thinner for a few hrs, we'll see soon enough. Do you guys think it could be the solinoids themself? Thanks

 

Why thank you. Mine's in the shop cuz i got hit in the side the 3rd day driving it . I LOVE THIS CAR.

Oh, by the way... my car idles at exactly 1000 and I never did anything to it. You guys think I'd save gas if I DID bother to "tweek" it like you guys are?

 

I doubt its the solenoid... post a pic of your engine bay... I think the BAC valve is just dirty... clean it with some WD 40... or some OIL DEGREASER... and make sure the shafts are able to move freely when pumped up and down...

 

He's right. take the BAC off, flush it with some intake cleaner...if you've never done it MRGSL-SE is right it will be dirty.

Also you should think about taking your TB off and cleaning it too. It's not that big a job and will help eliminate hanging idle, high idle and surging problems. Again..blast it with intake cleaner, then lube all the plates and linkages with WD-40 or equivalent. Oh it will also feel like a new car with a sharp throttle response.

You may also want to check the link below (on-line manual for GSL-SE) - See the emissions control section (4B) and on page 17 there is a complete trouble shooting guide on high idle or return to high idle - might be helpful (hope the link works)

Bump...

 

I think this is the link you are talking about.

Very good write-up worked for me.

Wow, thanks alot fellas for the links and the support. Hell, i should get a GSL-SE just for the support alone! much better than the politics in the 2nd gen section.

Well, as my previous post says i have the BAC sitting in some lacor thinner until tomarrow, if the problem persist ill do the same for the TB. I already have to soak and free up the 5/6 port sleeves so why not just clean the whole deal right? Thanks again guys

 

Yeah you're on the wrong forum for 2nd gen help.


No need to overdo it, but yeah clean it all out if you can. If you don't want to take the TB Off at least pull the rubber air funnel off and lube the plates.
