I have a 98 civic ex with a d16y8, 5 speed. 2 days ago I cleaned my engine bay. Now my engine started sputtering. Lagging up and down, and the check engine light flashes. It is fine at idle and to like 2500 rpm's but then the car just begins to lag in and out. Its weird because when I first start to drive it seems fine, but after about 2 or three minutes later it begins its sputtering. It almost seem as if its not getting any gas but i am not sure. I have cleaned the engine bay several times before and never had this problem and i clean it the same way every time. I would greatly appreciate any help. Thanks
