Took vehicle to dealer on 11/13/2002 with check engine light on. Dealer performed check and determined 2 02 oxygen sensors were bad. Said they would order them and call me to bring vehicle back in. Check engine light still on continuously. Engine speed rises and falls with no pressure on accelerator. When in gear, sudden engine acceleration causes vehicle to jump forward unexpectedly it is now 12/3/02. Dealer says sensors have not come in. When questioned as to whether this sensor problem is common with all Toyota trucks with 4.7 liter V8 engine. The service man was evasive saying there have been some problems. Considering they are having to order a part that is normally stocked at the dealership, and considering the unusual length of time it is taking them to replace the defective sensors on my truck. I am of the opinion that this is a widespread problem with the potential to cause accidents. This problem should warrant a recall of these type vehicles to correct this safety problem.
