Just recently replaced the stock Throttlebody with the SOS big bore throttle body and notice that when I accelerate it sorta lags around the 3k-4k RPM range? sometimes it will pop my check engine light and my oil kg/p gauge reads higher then it use to before the swap.Is this an ECU issue like having to reset my ECU to let it readjust to the air/fuel ratio?or do i have another problem in hand? I have also replaced my speed sensor (wondering if that has anything to do with italso. Any help would be much apperciated!.
