RE: bad sputter
Did you check fuel pressure? If the pressure looks ok, hit the throttle quickly, if the pressure drops more than 2 psi, there is a fuel supply problem. I can't say that a fuel supply problem is the only thing that could cause a ( bad sputter). It's just a place to start. If you can rule out the fuel system, then you can move on.

I replaced the coil packs this evening and it didn't seem to really help. But I can tell you this After the car sits and cools for a while it runs semi normal you still have to feather the peddle to go but its not as bad, Is this a sign of a bad O2?

As far as live vehicle data, what did the scanner show, about the 02 signal?
You might be able to borrow a fuel pressure gage for mfi system, it would have the fitting for the schrader valve. I'm not sure why your taking out the schrader valve, if that's what your talking about?

I'll rescan it to see what the O2 is saying. And yea the schreader valve is what I was talking about, My gauge is an aftermarket one I got from jegs for my daytona, It's just a 1/2 gauge and dont have the fitting to press it in without removing it
Thanks man
