i just recently rebuilt my motor and installed it when i hooked everything up and proceeded to start it.. it turns over fine but i have to pump the gas alot to get it to catch to actually get started.. but if i let go of the gas it dies, it backfires a little bit in the lower rpms but its fine as it gets past 2k or so this is the first times the car has been started so i mean .. anyone got any ideas or any info of what it could be not keeping an idel. i got lightweight flywheel and crank maybe.. the idel screw, tps sensor? or what?? maybe someone can help me thanks its a 4g63 gst eclipse new everything
