hey guys, ok i completed my b20 swap in my 94 civic dx, in which i used the stock harness and only switched over 2 plugs from the b20 harness, and have a LS computer, well anyway, when i hit the gas on my car the check engine lights start to flicker on and off and the car jerks really bad, like stalls or hesitates but does not turn off, but the check engine light only stay on for not even half a second. what might this be??? give me some suggestions, please thanxs
