the IMRC is what opens the secondaries up. if you look below your TB there is a round spring like thing just start your car rev it up over 4k rpm and if that thing doesnt move then that makes two people in OK that have bad IMRCs. I just pinned mine open. sucks til the car gets warm but after that isnt not bad at all
