Hi, the name is alfred. I have a 2001 1.6 litre accent. When I initially start my car it seems fine, in park or neutral I punch the pedal and the engines revs perfectly. The problem comes after the engine warms up or a few minutes a driving power seems to begin to diminish. when revs drop and I accelerate again (i.e. traffic light, stop sign, etc. ) instead of a steady acceleration the engine doesn't move, it stalls and even if i floored it the car wont move. It eventually starts moving but that stall is getting progressively worse. I have done some research but I essentialy know nothing about cars except the basics, what I did find that some similar owners have had trouble with this and one problem that I understand has to do with the mass air flow sensor.

I simply have no idea what to do because I dont know any mechanics. The milage on my car is 90k. recently had sparks changed, oil filter & oil, belts, time belt, head gasket, and brakes.

If anyone can offer their advice or tips I would greatly appreciate it, thank you.
