Accelerator cables take a lot of stress during driving because they are pulled all of the time in the course of a drive. As you would expect, moving parts create friction and heat, and these two things in combination hasten the wear and tear in any piece of equipment. It isn't really hard to replace this cable yourself, so if you feel like the engine isn't responding quickly enough when you step on the gas pedal, one thing you can do is replace the accelerator cable.
- Open your car's hood and locate the throttle lever. On older engines, this is near the carburettor. On most newer engines, you can find this by looking for the lever connected to a cable.
- Detach the old accelerator cable from the attachment by loosening the screw on the barrel clamp. From inside the car's cabin, particularly from the accelerator pedal, do the same, and pull the cable out.
- Inspect the new cable. Make sure that it is intact and free of kinks, cuts and rough spots, which could compromise strength. Before installing, you should also be aware of the gauge of the accelerator cable, so you know how it should properly fit.
- Insert the new cable through the flexible guide tube, which leads it from inside the cabin near the gas pedal outside into the engine bay, near the carburettor. First attach the cable to the pedal extension bar. Insert the cable into the barrel clamp and tighten the screw. Be sure that the cable's sheath lies firmly in the slots allocated for the cable. Otherwise, if this is loose, it might compromise performance, especially those lags you were trying to avoid in the first place.
- Pull the cable firmly from the engine end, so that it's taut. You can now insert the other end into the barrel clamp on the engine side, near the carburettor. Tighten the screw. Make sure that the cable is taut, so the engine will respond properly when you step on the gas pedal.
Now that your accelerator is responsive to your changes in foot pressure, driving will no longer be that frustrating. The pleasure of driving comes from the familiarity of a driver with his car and once a car fails to react to what the driver is doing, this might lead to a frustrating driving experience, or worse - an accident. You now have the peace of mind that your accelerator pedal won't break in the middle of driving on a busy street.
If you feel overwhelmed by these instructions, your best option is to take your car to an auto repair shop, to have professionals look into your cables. These services usually come with a warranty, so if something comes up again, you can always go back to have it repaired at the same shop. Whatever you choose, just make sure you know what you're doing, and that you are competent enough to do DIY fixes on your automobile.
