late getting to this job, as i really haven't had any symptoms lately. but i did remove the k&n filter to get access to the backside of the air metering device and disconnected the connector (it wasn't loose),looked at it..it looked back at me...it didn't look dirty, so i reconnected. so far no change..everything running normally. however, if i do hit the throttle hard, it will show some black smoke and i seem to be getting only about 17-18 mpg, even running mostly on the highway around 70mph. sounds like it's running rich to me..shouldn't i be seeing closer to 20-22 mpg?
