Did you ever get this fixed? If so, what was the problem, I have a 2000 Hyundai Sonata, 2.5L V6 and I have the exact same problem. But, I also I found that when I rev'd my engine it wouldn't go past 5000rpm and it would just sit stay at 5000 until I let out on the gas then the gear would switch and same thing would happen. There is a recall on Mass Airflow sensor on this year but mine was changed in 2003, I have a feeling its the pxygen sensor again, but can you confirm?
Thanks in advanced
