Well I had another thread on this problem and I thought it was my spark plug wires that I just installed because the problem seemed to start right after i did the plug install. Well I thought it was the walbro fuel pump because it gets so loud and the sound keeps changing and getting higher. The problem seemed to be gone until today I floored it to get over and sure enough the hesitation and power loss & jerking began again. Then I drove it for 3-5 seconds and it stopped. So I poped the hood and looked at the engine, wires plugs sensor connections ect, and I found that if I touch my a/c idle control valve and the vacum lines that go to it the car starts to die and then kills. I am thinking when I give wot the engine moves and this is picking up the ac idle valve and the vacum lines like when I touched them with my hand and it killed the same is happening when the engine moves. Any one know about a a/c idle control valve and the vacum lines. Mine has a air sound coming out of it. Its the bolt and spring with vacum lines going to it, not sure the correct name of it

are you sure your not hitting fuel cut? are you throwing any check engine lights? and if so what are they? you have to make sure the car is running, then put a paper clip or a wire or something in your diagnostic box, i believe its in E1 and T1 then go around the car a watch the flashing check engine light to see how many times its blinking. are you running 93 octane in it? what oil are you using? is the oil full? are there any bare wires showing or touching anything? are all your grounds connected to a good metal surface on the body or frame? all sensors are pluged in? how many pounds of boost are you on?
