when i start my 86 camaro in the morning i can rev the motor to 8,000 but when the motor is warm i can only bring the RPM's to 4,000 before it starts to kind die out or i lose throttle. i can drive it but i can drive it like i want to. Any Ideas?

 

so i cleaned the throttle body and it ran a little better. Could it be the fuel pump?

 

Check the fuel pressure.
