95 240sx KADE problems

[redlineracer 510]

So the other day i was at a stoplight and my car just stalled(auto BTW) so i tried starting it and it would crank but mot star. After getting home i found out that i didnt have any spark. So i replaced the cap rotor dizzy wires but left the sparkplugs alone because they had been changed 1000 miles ago with ngk's. so the car started up reset the check engine light and i drove it around no problems. Later that day when i was driving it started idling as if was about to turn off and when i came to a stop sign or a stop light i would have to put it in neutral and rev it a bit to keep it from stalling when i got home i realized that i have a check engine light and i count the lights on the ecu to verify what codes i had and what i came up with were 13,34 and 98, two of which are engine coolant temp sensor and 1 for knock sensor. So I replaced the ect and tried starting her up but the car still has a weird idle and after about 2 minutes started idling rough and cut off and right after i seen a a small puff of smoke come from the intake manifold area. I am really becoming frustrated with this car and I really need it to be running because i am starting a new job in a few days and its going to be very hard without my car.

i cleaned my throttle body recently i pulled my plugs out to find they were soaked with gas and when i tried to start it black smoke whould puff out the tail pipe with every crank it was pretty nasty.
