So still havent been able to track down what was wrong.. I have switched out maf sensors, map sensors, tb's, and checked all plugs and wires. A little more info as to whats going on. Take off is fine (1000-2500 rpms), but as soon as I get on it and hit 2500- 3500, it sputters like a bad tps sorta.. But switching out tb's completely didn't do a thing. So I got no clue.. Any ideas you guys? It's getting g rather frustrating.. Also got a video I'll put on YouTube of it happening.. Thanks guys..
