General Maintenance & Repairs - LS1 performance problem

All I am deploying next week and i am in Germany....My 98 Trans-am developed a problem. When i am cruising and i floor the gas pedal, the transmission downshifts fine then the car seems to start bogging down, almost as if it was starving for fuel. If i ease up on the accelerator its fine. The fuel pump is only 6 months old and no other issues with performance. The fuel filter is also 6 months old.

Any suggestions? The only MOD was a level 2 transmission and a 3200 stall converter just installed. The SES light is also on...

Id like to get this fixed before i go.......Any help appreciated

Put a fuel pressure gauge on it. Got to start with basics. And get the codes.

Visually inspect everything underneath the car fuel lines ect...could be a kink in the lines somewhere especially around the fuel filter...but like said above diagnose what the codes are also.

Maybe start by seeing what the CODE is thats setting off the SES.........

.

scann system with a gm tech 2 check for Stored DTC's and freeze frame data. check fuel trims and O2 readings, and get a fuel pressure test gauge on the fuel rail

Im not sure if they do or not but your A4 has a kick down cable? I had to re-adjust mine a few times but I couldn't get any real power from it until that point. My old trans was a 350T in a truck of mine. Not sure if this helps but its worth a shot i guess.
