Cant figure it out, someone help PLEASE!!!

this is what it does. It takes a couple times to start then when it starts it acts like it isnt gettin enough gas to go to idle, then after a few minutes it runs fine for a lil while or till the engine warms up then it acts like it has no power so u stick it in neutral and rev it up then put it in drive and go and then when u try to punch it, it tries to stall or gasp for air. I've replace the MAF, fuel pump, O2 Sensor, distributer, aux shaft, computer module, egr, water pump and radiator. If anyone can think of anything or have any idea what might be going on i would be ever so appreciative!!

A clogged cat converter can cause a car to die and will cause decreased engine power...............My 93 t bird had a skip in it and i replace all the ignition parts and it do anything so i replaced the fuel pump ......what a pain......works fine now......maybe that will help

I was havin a similar problem to that it would run terrible until it got warm but then it still sucked.....the problem was the TPS (throttle positioning sensor....it is the black box lookin thing at the end of your intake tube on the intake manifold of your engine...might want to have it checked....just a suggestion

Have you pulled any codes?

the only code it was throwin was for the MAF. Ive replaced it twice and reset the computer.

that is what mine was showing and later found it was that and the rear o2 sensors were bad.....the o2's in the headers were bad...again jsut a suggestion
