While replacing the plug wires could eliminate some of the lost power from the coil pack, the more likely suspect is lost cylinder pressure. In order for gas engines to fire solidly, a cylinder pressure of 100 PSI or greater is required. At lower RPM's this is some times not achieved due to worn piston rings or damaged cylinder head valves. At higher RPM's this will normally smooth out. Reccomend having your cylinder pressures checked at a local shop or do it yourself. The pressure tester can be purchased at sears or your local parts store. Simply remove all spark plugs, thread the pressure gauge into the head at the spark plug hole, turn your engine over for at least 3 seconds, then read and record the reading on the gauge. if under 100 PSI, that is your problem. Good luck! Replace the plug wires. Have the engine codes read. I suspect a random misfire.
A furnace filter should be used and should be changed about every three months. It is important to have one because they filter out dirt and dust which otherwise clog up the furnace and stop it working as well as it should.
Run a compression test.
mositure in gas, cloged air filter, some one changed carb settings,
Change the fluid and the trans filter; a dirty trans filter can cause this.
have you ever had the transmission filter changed and fluid changed?? Great place to start looking. If you have already checked the fluid level!
It has a permanent filter that is changed when you have the fluid changed.
Your tank filter should be changed every month. If your filter becomes clogged, it should be changed right away.
Partially clogged fuel filter or you are buying cheap fuel pumps.
There can be many causes for a whining noise in automatic transmissions. The least expensive thing you can try to eliminate the noise is to have the transmission fluid and filter changed. Some shops will only replace the fluid unless you ask for the filter to be changed, so ask.
Nothing terrible will happen but the old oil in the filter will mix with the new. I would recommend you change the oil and oil filter again. This will insure that you will have clean oil throughout the motor.
Some air purifiers do require a filter to be changed others have a filter that can be cleaned.
No, the filter can not pump. It is a filter.
