idle and clutch Options

[TSiwrx]

ok here's senerio 1.: back when i first got the gst, one of my freinds told me to take out the honeycomb thing in the intake. so i did. ever since, the idle has been a crappy. then when i got the TB gasket replaced, the car would die every time you push in the clutch, so i adjusted the idle speed screw out a little bit and now it sometimes stays around 1100rpm, but mainly is fluctuating all the way up to around 1500rpm then it will go back down to about 8-900. it does this all the time and im wondering if i caused this and what could be done about it. it still dies every once in a while after driving on the highway. would it help if i got another honeycomb thing (uh mines now a cat toy)?

2. my transmission sucks. it doesn go into gear the majority of the time. now, sometimes i notice that with the clutch pushed in (all the way), when i let my foot off the brake the car will start moving. kinda like an automatic does. this is not good. i was thinkin maybe the clutch needed to be adjusted. i dont know if these cars have a self adjusting clutch system or not.

any info on these two subjects is greatly appreciated.

You can remove the lower honeycomb from the MAS, but removing the upper will cause a poor idle, among other problems.

Sounds like the clutch pedal needs adjusted. Look at the VFAQ's... here.

1. First of all you only removed the lower honey comb right? If you removed the upper one you're going to need a new MAS or better yet switch to a GM MAF translator setup. I also have a used 1G MAS that I'll sell you, if you need it.

It sounds like your car is idle surging which is fairly common for an older DSM in this cold weather. If only the lower honeycomb was removed on the MAS then there are other possible causes for idle surge. Check out the crebotech website for these, such as testing your ISC to see if it needs repaired.

2. There are a few possibilities here.
-Your clutch slave cylinder is leaking and needs replaced.
-Your clutch master cylinder is leaking and needs replaced.
-You have air in your clutch hydraulics, needs to be bled.
-Your pedal assembly is wearing. Replacing the whole pedal assembly is a pain. So there are bandaid fixes for this such as a longer slave cylinder rod, adjusting the master cylinder rod where it connects to the clutch pedal. Putting a washer or two under the clutch fork pivot ball. (Transmission needs to be out for the pivot ball one.)
-You have a leak somewhere between the master and slave cylinders. (Not as likely as the others)

ok well i removed the one right behind the filter. im assuming that one is the upper one. Natedogg how much do you want for your used one? i prolly cant afford that, let alone a GM one.

Hmm? Both of them are behind the filter. When you look at your MAS with the filter off and the plug receptacle at the top the large rectangular inlet should have the upper honeycomb in it.

Look at the top picture on this page. This MAS has the upper rectangular honeycomb. The lower oval shaped one is removed.

If you don't have the upper rectangular honeycomb then I'll sell you my MAS for $50. Its in good shape and has the lower honey-comb removed.

I can't remember for sure, but the lower might have already been removed from your car... I'll bet you did pull the upper.... I've got an extra also, in case Nate's doesn't work out.

yeah i did remove the upper. ok i dont really have a job right now, so im not sure when i will have money. but i think ill take yours unless i find a better deal.

btw, im gonna try adjusting the clutch in a little bit and see if that helps anything

Big thanks to Rob on that clutch adjustment page. it was a really big pain in the ass, but the car actually shifts and goes in/out and up/down in gears. its so much better i am so happy. i dont have to turn the car off at stopsigns to get it in gear anymore. so thank you rob. now if i can just get a new turbo that doesnt burn a quart of oil in two days (im serious on that).
