Hello,
I own a 2003 Hyundai Tiburon with about 111133 miles on it. I just bought it from a private seller so I'm not completely sure about its maintenance history. It started acting strange two nights ago. I was sitting in a parking lot eating and I noticed the TAC falling and rising like it was having trouble staying on. I quickly finished eating and started to leave, but when I got on the road it didn't want to go. I gave it gas and it just kept stalling like I wasn't giving any gas. I was able to get it going and drove down the freeway home, but I had to stop at a sign and ended up pushing it from there a little ways. Yesterday and today it seems fine, any ideas?

Have a scan done to see if there are any codes stored in the computer.
