Hi Sir,
I have a Sedona A/T 2002, my problem just started yesterday while cruising in the highway. noticed that when i reach 60KPH parang nabibilaukan yung van the RPM ups and down just like engine breaking (kumakadyot) nakakahilo tuloy . pero kapag 0 to 50+kph wala namang ganoong problem. Tried to press the hold button wala namang problem until i reach 100kph but the RPM is very high due to it is in 3rd gear only.
i think yung van is trying to shift to 4th. im encountering the problem even i press or not the accelerator.

Last na ginawa ko is i change the Fuel Filter and air filter.

May problem na po kaya yung injector ko? is it marumi/barado? or is there something to do with the pump?
Hindi nga po pala mausok yung van ko, no sign of black smoke.

hope matulungan nyo po ako...

Thanks in advance!
