I just recently purchased A 98 Civic Hatchback HX.. I wanted to replace the intake manifold.. I heard the D- series manifolds worked.. Tried one out and the car didnt work, It just bogged out and sort of back fired but not to bad .. Put the stock one back on and now anti-freeze is everywhere.. Apparently it got in my injectors.. I need some serious advice.. My car is blowin out some white smoke at start up.. PLEASE HELP!!
