that looks almost indentical to a late 80's toyota i have its a very complicated little board inside the if u remove that sealed cover i had to remove the cover on my old maf sensor due to basiclly the conditions ur describing, basiclly jus one day i was driving and the car would not idle and would stall out unless i kept given it gas and sometimes even when id be going, well this happend to me in our bordring country of mexico so no where for parts so i poped the cover and took a cnady bar rapper and stuck it kind of as a stop in there to keep the sensor open more then it normaly would be allowed to be got me back to mexico not to mention i was pulling a late 80's chevy blazer with an old fire house type materail rope, what adventures. im pretty sure u may have bent that little mettalic sensor in there its very sensitive, it may be repairable but cross refrence the part maybe u can find one in a pic-u-part lot.
