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.

min e is doing the same exact thing, but before it started my car was running very rich,and spuddered, stalled it was a nightmare.i replaced distrubutor cap rotor, plugs,wires, o2 sensor, maf, temp sensor that goes to ecu......ended up bein ecu was bad.....but now my car hesitates at low rpms and if im not givin it enough throttle it starts to jerk a little if you have any idea let us kno plzzzzzzzzzzzz........its aggravating and its a little hard to slide a car thats running like this..

im still somewhat having the same problem but its not as bad as it was and somtimes i dont even feel it anymore. all i did was cleaned my plugs (i c you replaced yours) and i had a few air leaks in the intake pipe After the MAF. after sealing them up it ran alot better. i may still have an air hose leak somewhere around the intake so. im just work'n on it alil @ a time 'ill let you know what i come up with. good luck man.ps have you checked your fuel pump. it may be going out. i also had a loose whose on my fuel pump line in the tank you could tell it was loosing alot of pressure cuz it was real loose.
