All your doing is causing the car to switch to a failsafe fueling table that uses the MAP sensor as the air measurement device. There is a ton of things that could be the issue.

Hi out there,
In a previous thread which I posted regarding car running ok but down on power (The power boost from the turbo seems to be missing-the kick you should normally get above 3500 RPM) be I was advised to remove MAF sensor and clean it with electrical contact cleaner which I have now done. this didnt make any difference. If the engine is idling and I remove the electrical connector to the MAF sensor the engine will splutter for an instant and then resume idling normally. Is this indicating a faulty MAF sensor. Also when I do this the engine warning light illuminates and then resets after 3 start ups. If it is the sensor that is faulty and I replace it will the engine on board diagnostics need to be reset?
Go to an auto parts store and get the code read.
