Hi, i am new to the forums and seeking advise. I dont know if this has been answered before but i tried the search for anything like it and nothing has came up. When i accelerate it studders/chokes violently and it wont move. I have to barly put on the gas and it will slowly accelerate choking while doing it. I has gotten really bad and it is accelerating slower and slower. This problem stops at like 4rpm+ but when i floor it when it is like 1/2 of the power for a little while then speed up..... It didnt uset to do this. It also studders while idleing really bad and almost seems like its going to die. Does anyone know any leads on whats wrong? Ive replaced several things and nothing has helped.
