i have a 95 rodeo 4x4 ls & it's hesitating if you floor it when 1st starting out in drive & while you drive if u want power & apply gas it jumps/bucks every once & a while. & i've notice that the power drive light comes on after a while.. is there any power drive module or some other sensor i can replace? or vavle i can clean?.. Any advice is much appreciated.

nevermind.. dealer told me it couldn't be fix & the trans is probably shot, i put dry gas(2 bottles every fill up & a bottle of lucas gas treatment) & the problem went away.. i guess people never heard of water being in the gas tank..
