serious xj running problem

My truck is f'ed up. Two problems at the moment, also nss is bad going to replace tomorrow.
First problem, sometimes when I start the truck it will not fire. I'll have to flood start the truck but it will stall if I dont manually hold an idle. Truck won't hold its own idle. Occurs randomly not all that often though.
Second problem, when driving the truck "bogs" down. I don't know 8f its engine or trans. Rpms fluctuates on its own. Throttle is very unresponsive. If I push the gas down all the way ill get s popping noise from drivers side. Feels like throttle body problem, but I am stumped.
Only codes I'm throwing right now are 700 and 705, both for nss.
