TNight Posted October 22, 2012 Share Posted October 22, 2012 I am having a problem locating the cause of this miss. 1st Engine Code said Evap Leak 2nd Code Said miss on Cylinder 4 While driving the tach just drops off and then right back up almost like I hit a bump and it goes right back up ,at first it was intermittent, now it is anytime I drive, and the little dip on the tach goes from a little dip to bounce around like a geiger meter.It is not as bad when I keep the revs up or down shift ,but today it was so bad it was jerking the car like if your coming to a stop in to high a gear. So far I have installed nw plugs and fuel injectors due to it smelling like it was leaning out. Does anyone have a clue as to what is causing this. 98 Honda Civic EX Manual w/ a Cold Air Intake No other Mods Link to comment Share on other sites More sharing options...
TNight Posted October 24, 2012 Author Share Posted October 24, 2012 Tried to video the tach as it jumped around today ,but of course as soon as I turned the camera on it stop and ran smooth. But I did call King Motorsports in New Berlin WI. and got a firm an definate " It's your ICM" so tomoro I pick up a new distributor and for those interested I will let you know if it worked.
