I would start by checking fuel pressure and the TPS setting.

Good luck,

So which is it? stall or take off, I don't get this?

after i take off the car bogs for a split second then picks right back up where it left off.
Like other member said, TPS sensor. May also want to check your MAP sensor located on your intake manifold.

when i get up in the rpms it wants to make a sound like poop poop poop but it is only in really high rpms???
"poop,poop,poop" ? Sounds like your engine is taking a dump!

Have you checked for error codes? Have you checked your fuel pressure. May want to tape your FP gauge to windshield and observe readings while the engine bogs and poops....

When mine (87) through that code it ended up being the EGR switch-cheap fix, and I understand from this forum most offten it is the switch rather than the valve.
