ok so im almost 100% sure its not a trans. limp because i dont get a cel. Every time im in extreme and i floor it to jump around some one or in the case of the other day a woman just about hit me so i floored it to get around her and all of a sudden i dont have any acceleration. slow down a bit and thats when i notice its not revving above 2000 rpm. Fuel filter is new and i run power service cus its been real cold lately. Would a lift pump or fuel rail shim kit solve this?? Note it doesnt do this in performance or tow/econ settings. And ive noticed it doing this alot since winter started. Any ideas guys??
