20 Most Recent 1999 Kia Sephia Questions & Answers


Hello ayltaz: My name is Roger and I Will help you. The first code p0303 relates to a cylinder misfire in #3 cylinder. This could be a bad plug or plug wire. The second code relates to the crankshaft position sensor. You can just replace the sensor or have this problem tested as to replace a sensor because of a code can get real expensive and may not fix the problem. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

Sounds like you have installed the belt out of time. Check your alignment marks and re-install the belt.

No you may have a dirty idle speed control valve. Follow the instructions below to clean it.

Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
