car cuts out at mid throtleevery once in a while on and off making the car have a loss of power. at full throtle it does not do it. i cleaned the MAF. My dad had the same problem, he replaced his coil in his f 250 truck and it did not do it again. what is the problem?

 

check out the o2 sensor.. my car had the same problem. and im glad it was that and not something else. really easy to fix.
