Accelerator pedal has been sticking since the first year vehicle was purchased new. It has gotten so bad that in order to move from a stopped position one must keep one foot on the brake to avoid lurching forward or backward uncontrollably.

Throttle sticking closed
This investigation involves the general motors corporation (gm)throttle body (tb) utilized in model year (my) 1999-2002 silverado, sierra, tahoe, suburban, avalanche and yukon (subject vehicle(s)) with 4.8l, 5.3l, and 6.0l engines. The tb valve may intermittently stick in a closed position.in such a situation, an operator may apply additional accelerator pedal force to increase engine speed.the application of additional accelerator pedal force, to open a stuck throttle valve, may open the throttle valve more than intended and, in turn, accelerate the engine and vehicle more than intended and reasonably expected by the driver.on august 1, 2002, the office of defects investigation (odi), of the federal safety agency, opened this engineering analysis.the investigation revealed that two factors may cause the defect: 1) tb manufacturing process problems; and 2) accumulation of deposits (a pcv system by-product) on or around the tb throttle valve and bore.odi concludes that the tb performs in a defective manner after analyzing gm?s data submissions, and test data collected by the vehicle research and test center (vrtc).fifty-nine crashes are alleged to have occurred as a result of gm?s tb defect.the majority of the crashes involve a single vehicle, engaging in a close quarter vehicle maneuver (or low speed), and causing only minor property damage.four out of the fifty-nine crashes involve injury, and those injuries were minor.although gm?s tb is defective, based on the evidence gathered, odi has found that the accelerator pedal force required to open a stuck throttle valve is negligible, and the throttle valve does not stick in the open position.therefore this engineering analysis (ea02-015) will be closed at this time.the closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist.for a detailed discussion of the tb component and testing, please see the attached report.

What 1999 Chevrolet Silverado owners say
Most recent owner complaints, unedited.
Throttle body sticking on 1999 chevy silverado... I previously reported a sticking throttle body on my truck when it was new. It stuck at the idle position and took considerable effort to get it to "unstick". The dealer replaced the throttle body claiming the original had a bur, that caused it to stick. Now, several thousand miles later, the new throttle body is exhibiting the same behavior. It seems obvious that I didn't have one defective throttle body, but all throttle bodys at the time had a defect. I know that there are many similar complaints. I do not want to pay to replace what gm knows is defective. Please look into this matter further....
Consumer states: cruise control and toll haul didn't work correctly, when turned off cruise control did not operate properly, it kept accelerating when touching brakes. The toll haul command was telling the truck to down shift.*ak
While pulling away from a stop sign or traffic light accelerator pedal stuck. Owner contacted the dealer. Who recommended that the owner use a foam padding/ sand paper material and rub the inside of the throttle body.
The transmission was serviced more than four times while under warranty for the vehicle revving and sticking in gear. The vehicle has been maintained as it should have been. The manufacture offered no help. *jb the engine had come on, the fuel gauge did not read correctly, transmission slipped, the c control would not engage and a green and white wire at the pin circuit was loose, and the sensor in the washer jug was bad.
Whenever the engine warmed up it caused the accelerator pedal to stick intermittently, the accelerator pedal had to be depressed hard to get the vehicle to accelerate from a stop position. And the emergency parking brake would not hold properly when parked on an incline. Vehicle continued to roll. The dealer was notified.
The rotors rusted. The manufacturer stated that repairs were not covered since the consumer lived in new england. Salt from the snow caused the problem. *ak the pedal had gone to the floor, c/c light would stay on until the vehicle was shut off, the gas pedal would stick/throttle body, and there was a clinging noise, the master cylinder was inoperative, and the rear rotors were pitted and rusting. *sc
My 1999 silverado has developed a sticking throttle off idle creating a potential hazard in heavy stop and go traffic.
Accelerator pedal sticks, and driver has to depress the gas pedal hard to accelerate. Once the accelerator pedal engages, the vehicle accelerates to a high speed. On one occasion, driver depressed the accelerator hard and the vehicle accelerated and hit a dog.
While driving at any speed the throttle sticks.
