No, that's not likely the throttle body. start by looking at the throttle body though, if there are cables going to it that control it, follow the cables back, one should go to the firewall, and one should go to a little black box. that box is you're cruise control unit. chances are that is what's causing the problem (try a salvage yard, they're cheaper than a dealer). however if there is an electric motor controlling the throttle, you should take the car to a shop to have it fixed.

Car will not accelerate when gas pushed


Clutch plate and pressure plate seem to be too weak to pull the car. To test the clutch plate, park the car on flat surface. Pull the hand brake up, start the car, depress the foot brake pedal, depress the clutch pedal, put the car in 1st gear, press the gas pedal and leave the clutch pedal at once, while keeping the brake pedal depressed.
Follow one of the two following statements:
1. Engine does not shut down and remain start. (Clutch plate, pressure plate and clutch bearing defective - Replace all as a set)
2. Engine shuts down. (Clutch system is OK and does not require any repair).

Going highway speed on cruise control or not car will decrease in speed drastically and then you have to let of gas pedal and let it recover and then apply accelerator down again , this is continually...


Could be TPS (throttle position sensor). Could be a fuel related problem giving it to much fuel. Might disconnect your battery for about a minute, reconnect and let the computer relearn then drive and see what happens.

If set at a specific speed and you have to slow down by hitting the brakes, The brakes turn off the cruise control. Pressing resume automatically turns the cruise control back on and accelerates to the previous speed setting. You can also use it to accelerate and by releasing it the new speed will be set.

Cruise control how to use


Most cruise controls are designed to disengage when you press the brake pedal. I always mention this first because people tend to try to press the clutch pedal while the cruise control is engaged and this startles them when the engine revs up all the way...

Anyway, to use your cruise control:

1) Press the Cruise control button to on.
2) Drive up to the speed you need to go.
3) Press the "Set/Coast" button.
4) let go of the accelerator pedal

If the cruise control system is operating correctly, your vehicle will continue to travel at the same speed until you either press the brake pedal or you cancel the cruise setting with the cancel button of the cruise control.

Remember: Your civic is not equiped with a radar system for your cruise control, so if you are aproaching an intersection or traffic in front of you, do not expect the car to know it needs to stop. Also, cruise control only operates the accelerator pedal i your car, it is not autopilot, so it will not steer your car for you.

(you think it sounds silly that I am writing this? You should see my friend's car... He thought Cruise control was like autopilot, so he smashed his brand new civic into a tree...)

Happy Motoring!
