I've replaced my MAF and I still have similar problems. When it's cold it runs fine but as soon as it warms up performance gets poor. My engine randomly shuts off...and after I restart it(It starts back up fine every time) I get to 2300 RPMs and can't get past it, it just jolts violently. I have to closely monitor my rpms and accelerate like an old man to make sure I don't hit that magic 2300 which makes my entire vehicle convulse.
When I start it in hot weather it smokes ridiculous for like a minute as well
