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.

Dt: the contact stated there was a problem with the ABS and the wiring harness . When driving less than 10 MPH and applying the brakes the ABS activated. The contact's husband replaced the brake pads at least six times. Before the wiring harness burned the dashboard was hot. The dashboard lights, tail lights, headlights, and cruise control were not working.
When braking brakes failed, causing extended stopping distance. Dealership was notified, but did not resolve the problem. *ak the consumer crashed into a garage wall while entering. The pedal stayed up and firm and wouldn't slow the vehicle. Seconds later the brakes worked fine. The dealer stated that they couldn't find anything wrong.
When driving 40 MPH vehicle accelrated and the steering wheel locked up. Consumer was able to stop the vehicle, and consumer had the vehicle towed to the dealership for inspection. Mechanic was unable to duplicate the problem.

Consumer states while driving 60mph vehicle's speed dropped dramatically to 40mph w/o warning then increased back to driving speed. Consumer advised that problem occurs intermittenly. Ts
Vehicle has variation of sudden accelration; while driving 35 MPH, speed would continue if foot is removed from accelerator. Can be sitting in park, once shifted into drive/reverse truck will lunge with force. Please describe details.
Consumer states the engine speed does not return to idle when the accelerator is released, the vehicle will go 20 to 30 miles per hour on its own, the problem is more persistant when the weather is warm/hot, consumer reported the problem on several occasions only to be told there were no codes stored, finally the manager of the dealership drove the vehicle and determined the problem was a bad idle solenoid, they replaced it and that fixed the problem for about a year, the problem has reoccured and the vehicle is now out of warranty and it continues to run about 1000 RPM for a time after releasing from the accelerator.
Steering become hard whenever making a turn. Dealer notified, and informed consumer that speed sensor needed to be replaced. Feel free to provide any further information.
