my engine light came on w/code po105. can u give me an idea of what 2 expect

What is your question?

just came on again yesterday. it came on a few weeks ago but my neighbor re-set it. it runs good but revs high then low, when pushing on the gas kind of flutters then dies out on occasion. but recently i keep one foot on the gas and one on the brake to keep the engine from stalling. it doesnt always happen (stalling) and i am able to drive sometimes w/out the car feeling like its going to stall
