Ok so I changed the fuel gauge with another I had now it reads 42 with key on engine off but the pressure starts to drop...also with the car running its at 35psi...when I reinstalled the fuel rail I could tell the injectors are not sitting flush within its cup of the intake...and I can't push further in since the rail is flushed with the intake. So could it really be the injectors that are faulty?

There is another thread in general with injector swaps. Have you gotten the 24s yet?

Does it take time to relearn the 24lbs injectors or the o2's went bad already

Just a WAG but in my first post I asked about the o2s. You say they are running lean now. So could they be bad and telling the puter it is lean and dumping way to much fuel? I believe your came with 22lbs injectors but could be wrong.

Ok just read your thread again. Need to confirm your fuel pressue with key on not running and running.

Did you buy the injectors from slick *****? Or Jon at FIC?

Did not see where the o2s were changed.

I'm a complete moron, the reason for the sputtering was because it was low on fuel, didn't read the digital and it was on reserve

Ok so I put fuel the car responded awesome, even during close loop but when the car hit 230 it started bogging down on me. I went and bought a 180 thermostat which I plan on installing tomorrow...but now while I was driving it the asr turned on hooked up my scanner and gave a trouble code of tps signal out of range which brings me to my previous question about tps signal voltage. I get .58 at close throttle and 3.18v at wot is that normal?
