Emissions valve and related pumps failed causing a significant loss in power. This happened when traveling on the high way in upstate vermont. Suddenly my truck lost significant power, and would rapidly decelarate everytime I approach a positive grade in the road. Several times during the trip I slowed down faster than cars behind me expected, and the brake lights did not warn them as it was due to the truck losing power, and not me braking. In addiiton due to the location I was at I was unable to locate a dealer for several miles. When the codes were pulled for the service engine it appeard as code p2442 (secondary air injection pump system switching calve stuck open bnks).
Check engine light, vsc light, and 4lo light illuminated while driving. Response of engine became very sluggish - described as "limp mode". Dealer diagnosed failure of air induction pump.
Approximately two weeks ago I was pulling out of the ball park here in beckley west virginia when I began to accelerate my 2008 Toyota Tundra. The vehicle began accelerating higher and higher on its own sending me and my daughter on a 70 mph ride. The only way I could stop was to put both feet on the brake and put vehicle into neutral, eventually the pedal became unstuck and I drove the vehicle to my place of work less than a mile away and parked it. I called Toyota and they towed the vehicle in. This incident occurred after the safety recall. Toyota at this time cut the gas pedal in two and added cheaper floor mats. They said this was the problem. Today I was taking my children to school and was going up a hill. I depressed the gas pedal and had no acceleration. I gently rolled back down the hill and got the vehicle on the level and then took another route. I feel this vehicle is not safe. Its not the floor mats or the size of the pedal it is in the wiring, computer, or something. Both incidents were fortunate that no vehicle was in front of me or behind me. I called Toyota today about this second incident and all they could tell me was to call the 1 800 number. I explained I didn't feel safe in this vehicle, knowing that im putting myself and others on the highway in harms way. This is my mode of transportation so unfortunately I cant just stop driving it.
