Have a dodge 2500 ram 10-valve. After driving and warms up any extra strain on motor it starts to bog down and lacks get up and go will correct and drive normal a few mins then start a lite rev up and down. Have to pay with gas petal sometimes to get the motor to change gears (auto Tran). Changed tps ica sensors cleaned throttle and help pcv elbow. If I disconnect oxygen sensor almost all problems stop(sensor before converter) did not see any after converter. What should I try next?
