94 k1500 5.7 runs ruff until warmed up
When the motor is cold it idles fine and revs fine when the accelerator is pressed. When in gear and I press the accelerator the truck drives but sputters and lags a little until the motor is at running temperature then runs like normal. Could this be a fuel system problem or something else?

When I was a young man we had carburetors with the fuel pump on the front of the motor. It took about fifteen minutes to change them out. Of course, engine fires were more common with the cheap fuel hoses they used back then, but 12-16 PSI was normal, as it didn't take long for the float bowls to stay steady.I believe 16 PSI is normal if you have a TBI. If it's direct fuel injection, then around 60 PSI is normal.
