Default Lots of hesitation

Hey guys so I actually got to take my car out for a drive today for the first time in 10 months. Not with out problems of course. Anyways I took it for a drive and its got lots of hesitation and there is some poping in the exhaust. However if you get on it, it runs fine. Motor is a fresh rebuild and I does have a new opti. It does have a lt4 hotcam kit minus the springs which I changed out for some crane ones. Any ideas? I am glad its running and want to try to figure this out so I can fix it tomorrow. Ask questions and Ill try to answer them. Also it only has hesitation under load. When its sitting its fine.

check your plug wires make sure one isn't burnt, sounds like maybe not all the fuel is being burnt at low acceleration

spark plug wires are always the first thing to try, then plugs, coil, valve springs, fuel psi

alright. just go into a dark dark place like a garage or just wait for tonight and make sure there are no lights around you so you can see the arcing. and sometimes just because you dont see it doesnt mean its not happening. but check everything first. if it is your wires i have a barely used set up for sale
