Default finally drove my car

well my cars been in the process of gettting my Ai cam kit installed and i finally got to drive it today and the only thing thats wrong is the Idle..if you let it sit for an hour or two and get cold when you start it up it has a rough idle and wants to die but when it gets warm it idles fine in park but when you put it in drive it wants to die again then i give it a little gas and it idles fine till you push on the gas again and it like bogs down to 400 rpms and the oil pressure goes way down then it will bounce right back up..my tune is from pcm4less do you think it could be something with the tune or something else..when its idling good the rpms are around 1000 or 1100


btw it sounds bad *** but its way to loud with the cutout open but i have freaking flowmasters so i kno im losing some HP when i close to cutout

You need to verify that your IAC counts and TPS voltage is in spec.
