OK, I have a 2000 Accent bought new in 2000. It has 94000 miles on it. In the last week I took it to the dealer for routine maitenance (timing belt, oil, brakes, alignment) and they told me my MAF was bad. I purchased & installed a reman. MAF and the car started stalling. The dealer then replaced the MAF again as the computer gave the same code. Now it runs great in park but when you try to drive it the tranny slips in and out of neutral causeing lurching and revving. Any ideas on what could be causing this?

If the trans fluid is low or very dark in color, then have it serviced. If not, then please get it into your Hyundai dealer before you hit 100,000 miles due to the 10 year/100,000 mile warranty. They should take care of everythng for you. :2cents:
