Chevy engine problems

[Professor]

Tried cleaning the mass flow with cleaner, worked for twenty minutes but started acting up again will have to replace it tomorrow.  

You didn't just put in a K&N or clean and re-oil it did you. I've seen them get over oiled and cause it to coat the mass flow sensor with oil.

I still think you will be replacing them o2 sensors nearest the block. They seem to go out alot more then the ones after the coverters.
