Default Hard start, miss, air in the lines. Where to check?

Hey guys, I've had this problem well over a year now, but I'm just getting around to addressing it. I've always had to give a little pedal when starting, and its always had a little miss chug like thing to it until she starts to warm up. I was told it's air in the lines of 5 or 6. I'm not sure which. Where should I look to solve this problem?

it sounds like you have air in the lines
it could be your overflow valve an injector going to return or an old rubber line on the return side thats where i would start

Since I'm still slightly new to this whole injection system, and never have dealt with one before (I'm 17 ) how would I go about checking all that? Sorry bout me bein a newbie and all, but if you never ask questions, you never learn anything

Check all lines by motor. Pin hole will cause it to do it. Start it up and look around. That soved my problem
