hesitation during light acceleration, usually after turns

Purchased this car used and problem began at approx. 32k miles, and as of this time is still unsolved. Dealer found codes P0101 and P2299 and MAF Sensor was replaced. Car seemed to run okay for several days, but problem returned after a few hundred miles. NOTE: I cannot retrieve the"description of problem" page from here, but found another complaint closely associated with this problem. Likeness of their complaint to mine was that problem occurred following a right angle turn and during light acceleration. Also, length of problem was usually between 5 and 15 seconds. I, too, noticed the problem after several sharp turns, but also experienced on straight line acceleration uphill and again once when accelerating after coasting through busy intersection.

Like the previous post states, the problem seems always to occur when the engine is at normal operating temperature, and never when cold. As dealer could offer no solution other than replacing MAF Sensor I plan on returning to dealership when problem is more consistent and pronounced.

I've taken my car in 3 times now to kentville mazda, the first visit they put an unserviceable cylinder head assembly which took 5 hours. The second visit they replaced the same part with no fix. Now my third visit they ran more tests and still no fix. there's talk of they might have to replace the tranny.... bullshit, a brand new car, no f*cking way I'm continuing to pay for this lemon. a tranny goes in and should never be removed, the amount of sh*t that could get f*cked up doing this job worries me. I want a new car.
