Hi after dealing with my stupid vx engine y swapped an ex engine to my vx hb some sensors y coulnt wire them to the new engine ,and 2 litle hoses that i think they where conected to the vx engine intake manifold i could not conect them to the ex intake manifold.but y can feel the ex engine better than the vx engine and i kept the same vx tranny to the ex engine and i installed a p28 ecu. but i have 1 problem that when i shift from 1st to 2nd gear my car rpms drop low and i dont feel it so fast because the gears are very long. is it better to get an ex tranny???. and also the check engine is on, and the car is running very rich please help!!
