I have a 2005 Hyundai Accent today for a smog check, spotted a MIL on as the car brought in, feel like I am exciting to see what is going on with the MIL but I won't plug my scanner tool, refuse to inform a customer. I processed the smog inspection and then failed it for MIL on (referring to "CHECK ENGINE"). I found out the vehicle inspection report (VIR) paper reveals the this car have code P0303= Cylinder#3 misfire detected. The engine is real good no misfire happen on the dyno run, no problem. The odometer was about 55K miles on it. In few hours later, I got a customer ok to the emission failure diagnostic, found the spark plugs were worn out and too wide gaps then I smoke the engine for sign of vacuum leaks. No smoke detected. I recommend new spark plugs and air filter. Guess what? I saw the sludge build up inside the oil filler hole after check the dipstick for oil level and saw burnt brownish on the dipstick that indicates poor oil change maintenance. Obviously. The customer will bring it back for the repairs next day.
