I am running a gen v supercharger on a 99 gtp. ran fine with stock tb with blocked off gen v evap hole and evap line to tb and pcv from a gen pcv to fitting i made under tb. but now I put a N* and tried using genv evap sensor but wouldnt fit cause tb cable bracket would hit sensor so i drilled and put a fitting on the gen v evap hole and now using stock evap and connected it there but when throttle opens it hits the hose so i had to put my adapter plate of gen v to l67 tb in front of the gen v to N* plate so it wont hit the hose and pcv nipple in back of gen v to N* tb. Has anyone done this different? At first car ran fine and i was driving it to get fuel trims and come back to the shop and shut it down and turn it back on and its starts acting up. car didnt want to start. only way would if i pressed on gas a bit then idle rpm would be jumping up and down from 700 to 1200 then just die after a while. at some point after i turned it on i had press on gas to pick up rpms and it would smooth out for a minute then turn off car turn it back on and same problem rpms jumping up and down and car not starting unless i press on gas.
