What could cause a knocking noise in the engine?
Knocking is caused by preignition, where the heat in the cylinder causes the gas to ignite before the spark plug does. The noise could also be piston slap, which is caused by a worn cylinder wall. Try using a higher octane/grade gas and see if the noise goes away.
In certain engines like the Malibu 3.1 liter and others, the knocking is caused by a piston rocking in the cylinder. This is called piston slap. It is a damaging condition, but seems to be considered "normal" by GM.
Does a 96 Chevy Impala SS use synthetic oil?
You can use synthetic oil in any engine.
There is a caveat: if there is quite a bit of sludge build-up, the synthetic oil is likely to soften and release the sludge and it could cause problems.
Understand that the primary difference between natural and synthetic oil is that synthetic oil has essentially no paraffin. As oil ages in the engine the paraffin separates and sticks to the non-moving parts. Since synthetic oil has no paraffin, deposited paraffin will slowly dissolve in the synthetic oil and it's possible for large "chunks" of paraffin to float around in the oil and plug the oil pump pickup screen.

How long does it take to charge off an account?
The charging or writing off of a debt is only a required accounting entry by the creditor.
It does not effect you, or change the amount you owe, or that you owe it.
It does not change any of the legal methods to force collection that were available before making the entry. It does not change any of the creditors rights, or change your obligation in it. The debt is NOT forgiven.
All it does is make the creditors accounting statement recognize that an asset (your receivable) that it expected to realize, and already recorded as income, is not going to happen. they are taking the charge to their books for the expense of your not paying, or that it is now considered unlikely you will ay, and the asset does not exist (or in bank terms, is no longer productive). When the charge off occurs depends on many things in accounting parlance...most companies actually establish an account for expected bad debts (an accrual) as a current charge against sales, (expecting some to go bad), and adjust that account on experience...without having to do much on any particular account.

A musty smell in your car can be from a few different things. You may have water entering the vehicle from any number of places and it has gotten under the carpet. A leaking door seal, windshield, plugged sunroof drains,, etc. Or this can be a problem with the A/C evaporator drain is plugged and casuing a mildew build-up in the HVAC case. Water testing for a leak can be a very difficult task, since water can leak into the vehicle from a spot that is nowhere near the final resting point of the water. TechJK ------------------

How do you change a thermostat on 2003 Chevy Impala?
Inst. for 2003, 2.3Liter, V6 (2300)
========================
Before beginning, You will need a new thermostat (obviously) AND a new Throttle body gasket (apx. $1.50).
(remove hoses and clamps as you see fit...)
1. You will need to drain radiator fluid (at least partly).
2. Detach Throttle cable assembly (2 bolts in top, 1 nut bottom(front)) from Throttle body in order to access throttle body bolts.
3. Remove throttle body (2 bolts) in order to access the thermostat housing. You may run into issues with some hoses, feel free to disconnect and move them out of the way. JUST REMEMBER to reconnect them!
4. it will be easier to access the 2 bolts holding the thermostat housing to the engine by removing the exhaust manifold heat shielding, however, it may prove to be more trouble than its worth. you can access the bolts without removal but can be frustrating. Either way... its your choice.
5. The thermostat is housed in an aluminum, "J" shaped, pipe connected to the engine beneath the throttle body. Removal requires removal of the upper bolt and near removal of the lower (my vehicle has a slit in lower bolt hole so the housing can be "slid out" without complete removal).
6. once removed, you will have access to your thermostat.
CLEAN ALL SURFACE METALS of old gaskets and debris THEN replace your parts as you removed them. The thermostat itself has a gasket on it that seals up the housing. The throttle body gasket was (MOST LIKELY) destroyed during the removal. Remove any leftover gasket material. Be gentle! Remember, this part is trying to pull clean air from the filter. Any scratches and you may end up with a vacuum leak. The throttle body and thermostat housing should be torqued tight but not too much. Maybe 30lbs. I'm not exactly sure. Maybe another contributer has the answer to that.
Good luck! http://wiki.answers.com/Q/How_do_you_remove_the_thermostat_from_a_2003_impala
