acorns in air cleaner and tube to fender

My 95 ranger would run fine some days, and then other days just start bucking and loose power. I mean it couldn't even move in first gear., but it would idle ok. First i changed fuel filter and did the same thing a few days later. Was told it might be the mass airflow sensor, so i started to take it apart and found all the acorns and shop vaced them out. Am hoping this cures my problem and don't need to buy the nass air flow! Whay are your thoughts? thanks

Could be a blockage in the exhaust system causing back pressure. This can cause problems like your described.

Spray the MAF with aerosol electronics cleaner.
