1999 Sonata Idle Problem


  

csecsys -> 1999 Sonata Idle Problem (1/7/2008 6:04:02 AM)

I have a 1999 sonata GLS with 2.5 V6. The problem I have is that the car will increase idle from about 900RPM to 1500RPM randomly. It will sometimes stall and flood itself out. The check engine light is on most of the time. Reading the codes I consistently get F0301, F0303, F0305 and occasionally get F0125. The car will start after about 5 minutes and with the gas pedal pressed about half way down. HELP
