yea i seated the o ring poroperly i double checked before i put the upper intake back on. the only known vac line that is loose is the one for the fuel pressure regulator, but i had it un hooked before the swap and it didnt change the vac.

do you have cats or have you removed them and how is your fuel mileage

eh i get like 14 mpg, i have Hi Flow cats, and super 40 flowmasters. and at first start up the rpms will fluctuate on there own like ill start it and have to hit the gas pedal and keep giving it gas till it can idle on its own, then it will idle up and down just sitting there.. i had to back out the idle srew on the troghtle body because otherwise the throughle get stuck open at around 3k and then will eventually go back to 1k or 900 for idle, so i had to drop down the idle to about 600 rpms wich i think is to low.

well when you play with the idle adjustment screw that will alter the tps reading and affect learned idle.....what you really need to do is make sure the IAC motor is clean by removing it and cleaning the pintle and after that perform a idle relearn and set the tps in the process to a nominal setting of .92-.98 volts and after base idle is set perform a idle relearn after reseting KAM by disconnecting the battery...it's listed in the stickeys or perform a google search and you'll find all availible info
