I'll keep this short. I just had my Camaro parked for a couple of days to replace the rear end gears. When I started it up today to see if the gears were okay, the car would not idle without be feathering it. The idle was poor and choppy as well. If I rev it above 3000, it runs fine. If I shut the car off, I can hear fuel trickling down the secondaries and confirmed this by taking a look after shutting it off. It ran fine when I parked it a couple days ago. Very confused as to what could've happened. Also, it doesn't seem to be heat related because the car did it nearly instantly after a cold-start. Finally, if I start the car up again, it will idle fine for about 10-15 seconds, and then it won't idle by itself/gets choppy/dies.

This is on a 360cu with a Holley double pumper with Holley HP main body and mechanical fuel pump.

Any input is appreciated.

 

It was the needle and seat on the secondaries. Threw a new one in - problem solved.
