sluggish bog intil 3000rpm

[plane16j]

i was thinking it was the fuel pump, but most of the time the car starts up fine.when i press the gas the rpms bogs/sputters slowly up to 1500 drops then bogs to 2500 then cleans up after that...then it will kinda bog i punch it 3/4 of the way until i catches up with its self, at high speeds it will slightly cut in and out if i dont slowly gradually increase throttle. i still kinda think its the fuel pump . but usually when the pump is going out cars will jolt and jerk. but mines not really doing that.please give me your best ideas thanks.p.s. it only dose all this after it warms up.

Disconnect your throttle position sensor and see if the problem resolves. If the problem resolves, replace the TPS.
