92 Camaro 3.1 the more throttle I give it the less power I have

There are some very knowledgeable people on here, along with a huge number of threads with this exact type of issue that could help. However, you really need to give some more detailed information on this so that people could help, (IE-does it idle fine, have you recently changed something, are there codes?), otherwise they tend to skip over the vague request for help. Just my opinion/hope this helps you get what you need.

Sounds like a bad fuel pump to me... but that is just a guess.

OP has some troubleshooting to do.

If the car starts and idles fine, first thing I would to is check the fuel pressure at curb idle then increasing RPM.

Good luck

Yup, sounds fuel related.

I'd suggest monitoring the fuel pressure WHILE IT'S IN THE ACT OF SCREWING UP; as opposed to, sitting in the driveway idling happily.

Tape your gauge to the windshield and drive the car. See if the pressure stays correct while it's malfunctioning. If not, at least you know which system of the car you need to be working on. Possible causes of problems might be the fuel filter (you HAVE changed that, right??), fuel pump, regulator, injectors. Not as likely to be injectors since for them to be the cause, they would ALL have to be failed the same way by about the same amount; not impossible, for example by being clogged with debris, but not as likely as ONE part that could be THE single point of failure.
