What could this be? I need help please

SOURCE: sticky gas pedal

it is a dirty throttle plate. $280 is an absolute ripoff for a cleaning, it is about 10-15 minutes of work. They are probably quoting replacing the throttle body which about a $150 part.

Got to Autozone and get "CRC Throttle Body Cleaner". Remove aire inlet hose at throttle body with a screwdriver. Spray a *small* bit onto throttle plate, use clean rag or qtips to remove gum/varnish. Spray pivots and also clean around perimeter of the plate. Take it to an independent mechanic if you are unsure of the procedure.

Find put where the hissing noise is coming from, you have a vacuum leak. Fix that , and everything else will be fixed. After you fix it, disconnect the battery for 5 minutes to reset the computer and fuel trims.

It is the booster, but it might not be abnormal.

Vacuum from the engine is supplied to the booster, and vented if the brakes are not being applied.

When you step on the pedal, the movement of the pedal blocks the vents, allowing the vacuum to build up. That vacuum then pulls on a diaphragm, assisting you in applying the brakes.

Most people can’t hear that venting, some can.

You should, of course, have it checked out, but it sounds as if this might be normal operation.

The booster is bolted to the firewall, and then the brake master cylinder is bolted to the forward side of the booster.

To replace it you disconnect the brake pedal, remove the master cylinder, take the vacuum line off the booster, unbolt it from the firewall.

Install the new booster by reversing these steps.

But I don't think you need one, from what you say.

If your brake pedal is soft then you problem are very close what is called metal to metal on you'r pads. Either that or if you have rotors a common thing that will happen is that they may bet warped. Warped rotors is a condition in which the rotor glazes over and gets a shiny look to it. When this happens the brake pad will not catch the rotor as well and cause a vibration at brake. Try removing the tires and inspecting the brakes for any of those conditions. Honestly for the thumbing sound it may be a brake issue as well or a syspention part that is worn. Pep Boys does free brake inspections in most states, you can bring it over to them and have it tested for any of those conditions.

Hope this Helps!
