Hello I have a 00 civic coupe ex with d16y8 engine and my cel keeps coming on and when it does it changes the driving completely... example: after about 30 minutes of driving after it comes on it will be in gear and when I let off gas it will be rough not smooth like usually when the cel is not on. So I got tired of seeing the cel and disconnected the battery for ten seconds and the problem is completely fixed I thought it may be my vacuum lines but I checked and triple checked them and they are fine. Its a really annoying problem thanks for any help in advance...another note. My dash and headlights seem to always flicker could this be connected? This problem happens at least twice a day and i can't figure it out
