How to Replace the Throttle Body in an Acura Integra
- 1). Take the motor out and check your cylinder chamber for cracks if your car isn't working properly. The fuel and air are mixed in the combustion chamber; spark plugs ignite a spark which then starts an explosion. The explosion pushes the piston down which turns the crankshaft and makes the car go. The engine runs roughly--or not at all--if part of this system breaks down.
- 2). Check if spark plugs are worn or covered in carbon. Faulty spark plugs won't ignite the fuel and air mixture properly, so the car won't run properly. You'll need a spark plug socket with a rubber insert to remove the plugs.
- 3). Empty out the fuel tank if you suspect stale or bad gas which doesn't vaporize properly. Look for rust in the gas lines that can clog the fuel filter and fuel lines. Change the fuel tank, if you find rust. You'll want to support the fuel tank on a hydraulic jack during the removal and installation process.
- 4). Tighten your gas cap if it isn't sealed properly. A loose gas cap can cause problems like excessive fuel consumption or the engine not running properly.
- 5). Inspect your fuel lines to see if they are broken, rusted, clogged with rust or pinched. You may have run over a rock or something hard. Check the bottom of the car for a hole and leaking gas which can be dangerous or can cause you to lose fuel.
- 6). Change your fuel filter if it's dirty or clogged. You car won't run properly or might not start because dirty fuel filter can starve the engine for fuel.
- 7). Look at your carburetor or your fuel injector if the engine is running roughly or not firing properly. The carburetor feeds fuel to the engine. Look for worn parts or components clogged by the build up of varnish or dirt. Check if your fuel injector is clogged with debris or varnish. You can use a mechanic's stethoscope or long screwdriver to listen for an audible clicking sound.
