2002 Buick Lesabre 6 cyl 58000 miles

My service engine light comes on one day, off the next, then on again the next day, etc. Thje engine bucks on hard accelleration.

I had Auto Zone check for codes and found code P0102, having to do with the MAF/VAF. I found that the rubber boot was not fully inserted on the air filter housing and had a small gap on the bottom. I fixed that but still have the problem.

What should I do now and how do I reset the code assuming I can fix it myself?

Thanks

Thanks for your quick reply. I bought some MAF spray cleaner and I'm going to try to clean it myself but now I need some help locating and removing the MAF sensor for cleaning. The car has several electronic modules in the vicinity of the air intake.

There is a two wire sensor in the rubber tube between the air cleaner and an aluminum housing connected to the engine block. On the aluminum housing there is a module with 3 wires labeled A B C. To the left of that there is a 4 wire module and below that module there is another 3 wire module. Which is the MAF?

If the MAF is in the aluminum housing, how do I get to it? There is a screen on the intake of the housing so I can't see or access the modules through there. Do I have to remove the aluminum housing from the engine block? I hope not because there is a lot of stuff connected to it. Can I remove the screen? Can I remove the MAF from the outside of the housing? Are there any precautions I have to take?

Thanks for your fine help.

David
