It should be an inline filter on the passenger side located under the car near the rear door.
Doesn't have one so let's just say you did! PapaJohn
No.
Should be under the car on i believe the passenger side, it is one of the canister filters. Fairly simple to change.
Kind does not matter but the weight does. It requires 5 quarts of 5W-30 with the filter change.
Short answer: no. A clogged fuel filter can cause difficulty starting, poor performance, and inability to maintain speed. These symptoms have very little to do with fuel economy. Change the air filter instead.
You will need to drop the transmission pan and replace the gasket. While you're at it, replace the filter and clean the pan.
A 1994 Chevy Caprice which has lost all power has the ignition timing set incorrectly, bad spark plugs, or a dirty fuel filter. If all components in the engine do not work perfectly in sync, power and performance are easily lost.
behind the rear plate
I'm assuming that you mean the cabin air filter not the A/C filter, however there is no cabin air filter in a caprice, i have owned several of them. Air Sponge Filter co. offers a full line of furnace filters, air conditioning and ac filters for home or office. http://www.airsponge.com
the fuel filter is on the carb. you have to take off the fuel line
its located on the bottom of the air filter
