Hey guys my 1974 260z is having issues when you start the car and don't have a load on it runs OK. you can hear some kind of a miss. when you start driving down the road it bucks (only way i know how to explain it) it acts like its not getting enough gas. so i replaced all fuel filters and did a rebuild on the carbs and checked all my grounds...added a motor to body ground because i couldn't find one, replaced coil, cap, plugs, wires all that stuff and well nothing i seem to do changes the way the car is running. after replacing the plugs ran for a few minutes and the plugs have alot of carbon on them Ive played with mixture and it really don't do nothing..also i cannot get the car to drop bellow 1k RPM without it sounding really crappy. what do i need to check next
