Having problems with your 2004 Kia Rio ?

I recently moved from Texas (Dallas) to northern Calif in the Sierra Nevada mountains (altitude 5400'). In the past month my 04'[ kia rios 1.6 would run fine for about 45 mi's &n then at a point I would let off the gas cresting the mountains & then I couldn't accelerate past 2500 rpm. Now if I would stop & shut the engine off & restart it, it would continue on like nothing happened. I'm guessing the altitude has something to do with it & might have something to do with oxygen sensor.

Answers :

The MAP sensor (Manifold Absolute Pressure) in extreme situations like you are listing requires a restart to adjust for the altitude.

This is not out of the normal, if it continued to run poorly after the restart then you would have an issue in which a different MAP maybe called for. I have personally seen cars that take as long as 3 days to adjust properly. (IE in my example: 907ft to 7854ft over night, took more than 2 days to correct)
