Problems with 2005 Kia Sedona POWER TRAIN

While driving at approx 55mph on both a 2 lane hwy and the interstate hwy, the van would suddenly make a loud bang sound, jump, and the rpms would go up to over 4000 and sound like it was in 2nd gear. eng light code said intake trans sensor, which i had replaced. same problem happend 2 more times after that and still not fixed.will work for a while after shutting car off and restarting it but same problem happens after about 20 miles. code still reads intake sensor problem each time. i tried using off brand sensors the first 2 times and an authentic kia sensor the 3rd time. there was no difference in performance, just the cost of the parts.

I was driving down the road when the clear road turned into black ice going around a corner, i then got pulled into snow and then side swiped a telephone pole that sent me into a boulder bigger than my car. the impact was at 30mph and the air bags were supposed to deploy between 7 and 10mph. my head when into the windshield 2 times and bounced off the steering wheel. my wife slammed her head off the dash and my daughter had a seatbelt bruise. the air bags never deployed and kia has a so called fix for the airbags but its still not out or recalled yet. when the ambulance showed up they hit the black ice and almost slid into us. about 20 to 30 mins after the ambulance showed up the town had a salt and sand truck come out and fix the corner. on the way to the hospital the emt told me i was the 5th or 6th person to crash in the same spot this year. and the year had just begun. but more importantly the engine was pushed back 2 to 3 inches and i have pics and video of the damage. the airbags could have saved us a lot of pain and suffering and huge hospital bills. *tr
