I NEED HELP IMMEDIATELY
My 1992 Camaro RS (305 TBI) isn't getting enough fuel, I start it and at first it idles perfectly but after about a minute or 2 the idle bounces, it'll struggle to stay running, if I put my foot down and hold it at about 2000rpms it will go there and cut out, and fight to maintain the same rpm, and when I drive it, it sputters and cuts out like it's going to die until I put my
Foot down and then it goes, but after that it starts again, this problem occurred before and it was a bad battery connection, I fixed it and it stopped, now I've replaced the battery cable and when I got it
About 5 months ago I put in a new fuel pump and filter, battery is good, fuel pump is 5 months old, connections are tightly in place, what's causing this? Thanks in advance!

 

I'm not too terribly familiar with throttle body injection, but a few things come to mind. Dirty injectors, not enough fuel pressure, fuel pressure regulator, poor electrical connection, or possibly something to do with the ECM.

I'd start with checking your fuel pressure since it's the easiest to check. I believe I've read that it should be around the 12PSI ballpark, but I I'm not certain.

 

Verify fuel pressure, then connect a scan tool. You'll find clues to the problem in the data stream.
