SOURCE: how remove the rear inside door panel on a 2001 oldmobile aurora

The inner door panel is held in by clips and screw.
Look at the door near the door handle there should be screws holding it in and along the outer edge of the door. Once loose, and the door handle removed or the arm rest removed. The door panel then prys out , because of the clips that hold it on. Then pops out by applying pressure to the panel upward to the top of the door. The clips always break because of the design and plastic.

Good luck

SOURCE: need to replace the superchager belt, i know that it isn't easy, remove the lower moter mount spacer of the idler pully mounted inside the mount? '96 riviera

If memory is correct it should be driven by the serpentine belt, which runs through one of the engine mounts. 
To change the belt you'll need to support the engine (by something other than the oil pan) and pull the engine mount. 
== here is another opinion== First you have to remove the belt to the alternator then you can remove the belt to the supercharger. To do this you will need a 19/32" socket and breakerbar or long ratchet.  
Put ratchet on belt tensioner nut and pull toward front of car then pull belt off. There is a separate tensioner for each belt. 
I hope this helps and since your doing all that work might as well sevice the supercharger too which is always forgotten.
You can buy a superchaarger lubricant from the dealer or, according to the manual. You can use synthetic 10W30 weight oil, which is a much cheaper route. 
The filler is a small plug located at the bottom of the goose neck of the supercharger. You need an allen wrench to unscrew it. The oil should be up to the bottom of the threads for the screw plug.
Good luck and hope this helps. Dubble check though, i had a long day.

They are usually in there pretty tight. If drivable, you can have someone loosen it up with a shop air gun.
Thread is not reverse.
There is a second way to remove it...Use a solid 1/2" breaker bar with the correct size impact socket. You need to support it and brace it against the floor. Then "bump" the engine over Don't crank, just bump. The engine crank will unscrew itself from the bolt. Be careful doing this if socket and bar get loose they can damage you and stuff around the area where you're working. I use a pipe driven into the ground with a pair of vise grips attached to the breaker bar to keep it at the right height. (bar goes inside the end of the pipe)

SOURCE: Engine Won't Idle

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

My idler pulley on my 96 ford explorer is grinding on the bracket that holds it in place and creating a loud grinding noise, what steps would I use to resolve it??

change the idler pulley . its held on by a bolt in the center of the pulley. the bearings are sealed so you can't grease them. but first you have to take the tension off the serpintine belt. that is also another pulley located below the idler.don't know what size bolt on a ford but use a long wrench grab the bolt on the tensioner push to the right like you were tightening it. that will release the tension on the belt. don't take the belt all the way off just off the idler pulley. change the pulley and do tha same to reinstall the serpintine belt. if the belt comes all thr way off under the hood or on the front around the top of the radiator there will be a schematic that shows you how the belt should go around everything. let me know what happens. sometimes the tensioner pulley will grind also so be sure your changing the right pulley

My 96Lincoln towncar , 1 of my pullys are squeking I replaced the easiest 1 u recgonize on psgr side in front of engine were belt/pullys are. It doesnt squeak sitting still only when Accilerating , and if...

Sometimes the A/C clutch pulley goes bad. It is a combination of a clutch and an Idler pulley. This means the part is always turning the bearing regardless of whether the A/C is on or off.

But you can try to change out the tensioner and idler to see if they help. Parts vary widely in price.

As for A/C pulley, some are removable without taking off the compressor. They have left-hand thread and a small clip. Require grinding out bearing assembly and punch pinning new part to hub. Often can be done in an hour by the ambitious.

Would think that roughness in bearing as you checked could be judged as good or bad.

Lower idler pully seized. this is on 3800 vc supercharger {Pontiac} 96. do i have to pull motor to replace pulley?

You shouln't have to.
It may take a little longer to remove and a lot of patience.
If Alternator, or AC or power steering in the way, take them off the engine and put to one side, DO NOT disconnect the AC, just remove if in the way

Trying to replace the idler pulley and can't get the motor mount bracket out to access the pully - any suggestions?

i'm in the same boat as you. this appears to be an exceptionally fun project! in order to remove the motor mount you need to make sure you have a engine hoist to support the load. perhaps you might be able use a good floor jack and try to support the motor from the bottom. In any case when the motor is propped and the load is balanced, the motor mount should be easy to remove -- just take out the 4 bolts. if however the weight of the motor is not sufficiently supported then it can truly be a nightmare to remove the mount. after removing the mount you can remove the other bracket and finally have access to the idler pulley!!

How do replace the tensioner pulley on a 2.2 engine 4 cyl. 1998 chevy cavelier .

there are two bolts located behind the pully on the mounting bracket arm, (you have to use a 1/2 inch drive bar in the idler pully to move it so you can see the bolts) That will help you with locating the bolts, while you are moving the pully you might as well take the belt off to save time, After you remove the old idler pully install the new one, use your 1/2 drive bar on the pully to put your belt back on. Pretty simple job, good luck!

check the idler/tensioner pully's and the alternator pully, there is a common problem with one of these 3 going bad, usually an idler pully the best way to check is to get a mechanics stethescope and touch the end to the bolt on the idler pully's you will notice a very distinct sound difference from a smooth pully and one with bad bearings. gm tech here, seen many of these
