Does it not want to accel above 35 mph? Is it a 4 wheel drive model? Have had Rendevous that have abs sensor problems in front wheel and will activate traction controls, with no codes in engine, however there will be lights and codes for abs problems. If this is case, try unplugging abs and trac module connector, then drive and see if it accelerates now. If now accels, you have to repair abs.
