well i had this problem that i thought was fixed...I would give it some gas and it would kinda just not move...i would get from 60 to 80, probably 10X faster if i had the gas pushed 1/4 of the way versus 1/2+ of the way...

thought it was the TPS sensor and the MAP so replaced the TB...and O2 sensor, well fixed it for a while, now its back to the same old, but only in 4th and 5th gear....1-3rd i have power in all RPMs. 4-5 I would be lucky if i could make it to 60 on the on ramp to the highway. also there is some studering under acceleration

But tonight i was driving home, and all was the same untill one time, i pressed the gas, and it was stiff, but I got up to 90 like it was nothing.....did it all the way home and it felt good, but i kinda want to know what the symtoms might lead up to.....]
new,
TB, Intake, o2, wires, plugs, fuel filter....

need help thanks!
