On3 Foxbody warm Start problem

Hey Guys I just put a on3 70mm kit on my car(1989 fox) So the car starts and Runs Parked perfectly Idles Great. So here my Problem

1.starting the car in [coldstart] then start to drive the car for about 5 min and come to a Rolling stop the Car will stall out. Then I'll try to start it but it only cranks? Then I floored the gas and crank it and it starts but starts to Miss and won't rev up at all even if the pedal is Floored.

2.If I start the car [cold start] It will run forever..but when I turn the car off it won't start up unless I Floor it and after it starts I have to keep it floored so the car will stay on But has a misfire and won't rev up at all.
