2002 Kia Sedona check engine light
I went to get the Sedona inspected. First the mechanic said that my O2 sensor on the bottom was bad. So I replaced it. Then the mechanic said that the other O2 Sensor on the bottom was bad. So I replaced that. The O2 sensor problem went away but, then when the mechanic used the analyzer, the analyzer said that the Mas Air Flow Sensor was bad. So I bought a can of MAF cleaner and cleaned the MAF sensor. I took the Sedona back to the mechanic, the hand held anaylzer showed that everything was working properly, perfect except that the check engine light is on. So he hooked it up the the computer that the state uses for inspection and the computer says that the vechicle was not ready. I drove the Sedona for 50 miles before I took it to the mechanic so now we both do not know what is wrong with the Sedona. It has 193,000 miles. Any ideas?
