TNight Posted October 23, 2012 Share Posted October 23, 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...
Mac Lovin Posted March 8, 2013 Share Posted March 8, 2013 deff do a compression test on the number for if your getting a code, as for the jumping high idle, throttle position, idle air control, fuel filter, check fuel pump Link to comment Share on other sites More sharing options...
