What would cause 2004 Rodeo 3.5 liter to dog out from 0-20 then take off from there extremely fast from 25 and up mph, and also turns check engine light on it runs great no matter where I go, but when taking off from dead stop to about 25 mph its extremely boggish. Then when it hits about thirty mph it gets up and takes off like it should wit no problem. Check engine will come on every 3-5 weeks driving it everyday

I have also done that and it will not get the check engine light to come bck on, when I need it on its not lol. It is also doing way worse on gas now but doesnt have any problem starting or running it is just way hesitant taking off and it hasnt kicked the check engine light back on in well over a month now and I drive it everyday, I am pretty much lost on where to go besides it being the O2 sensors being bad. Would those being bad cause the problems I am having?
