I did a search on this, but for some reason, when I put in "Code 33" for the search engine, it gives me an error message. Anyway, this is what is happpening as of late. Code 33 comes up. I have a new MAFS, new 02 sensor, new wires, and new MAFS burn off relay and power relay. Car hesitates, idle jumps up and down for a bit...but when I hit gas, it seems to go. The light doesnt always come on eihter....today the car wanted to stall, and the light didnt come on...but it then it was fine. I'm lost here....I cant figure it out....can anyone shed some light on what this could be and what I can do to correct this annoying problem so I can continue on with life and stop wasting my time fixing things that should already be fixed?? Its getting really frustrating and annoying. Thanks for any help.

 

Make sure the wires going to the MAF are in good condition. If they are going open or shorting then you will have intermittent problems.
Also make sure the connector plug isn't loose.

 

Thanks for the reply. I believe i checked all those connections and they all look good and are tight. I dont know what else it could be.
