Okay so i bought a new s13 sr20det swap off of someone here on the forums not too long ago. It was put in about a month ago by a shop and i have been trying to tweek it and get it running good since then. The car will start but idles badly and doesn't drive too well. If i take it out i'm scared it'll stall out and ill be stuck. When i give it gas it doesn't feel like its putting down the power it should. It will take a bit for it to rev up and when i press the brake pedal in it will only go about halfway in then i cant press it anymore. If i try and hold the rev at 3k while at idle it can range from 1500 to 4500. If i leave it alone it sometimes idles at 1200 or 500 and in between. If left long enough it stalls out. I have checked everything i can think of and it seems everything is hooked up right. I am not a master mechanic as i am only 16. Any help would be greatly appreciated! Here is a list of supporting mods on the engine:
Stock s13 sr20det ecu
Stock sr20det mafs
new ngk spark plugs
isis intake manifold w/stock t/b
dc sport bottom mount turbo manifold
GT2871R turbo

Unplug your MAF while it's idling... If it smooths out you need a new MAF.

I tried that, and it smooths out for a bit then after a couple seconds it stalls. Another thing i noticed is that when i pulled off my filter i saw oil inside my maf. and filter. Is that normal?
