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 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.

Try cleaning your maf....you can get a can of the cleaner (can't remeber off the top of my head who makes it but if you walk into autozone and ask for a can of maf cleaner you'll be cool and only like 6 bucks). Sounds exactly what my S14 was doing a few weeks ago and the 15 minute maf job did the trick...Good luck dude
