Whats goin on guys i have a 92 camaro 305 tbi and im having this problem. The other day i tried starting it and it just cranked but later that night when i tried again it ran, but really lean. Revs were low and i mean like 400rpm. It will rev up when i gradually depress the accelerator but if i drop it straight to the floor it stalls. Any ideas on why? I'm 17 and i'm used to carburetors this is my first fuel injection car.

Im not as knowledge able as some of the people on here, but I will give you a few suggestions. Id check all the vacume lines at the throttle body and where ever they run map sensors ect. There are many things that can cause this however your sort sounds like a fuel pump going so Id check the fuel presure? A vacume leak is a cheap easy fix start with the cheap and work your way tward the things that cost more money.
