This may be a sticking exaust valve. The next time it starts skipping drape an old rag or a tee-shirt over the tail pipe. Notice how it is blowing away from the tail pipe? If at any time it sucks into the exaust pipe, especialy when it "skips", it is probably a sticking exaust valve.
Do not change any sensors unless you test them first and determine that they are bad. The good thing about computers in vehicals is that if a sensor is bad the computer sets off a trouble code. This makes the check engine soon light come on and you then can get a code from a scanner leading you to the problem. Just blindly changing sensors will cost you more money and cause your blood pressure to rise to unhealthy levels if the problem is not the sensor you replace. Keep me posted
