I went to the drag strip last night made one run no problems. On my second run i got half way through 2nd gear and the car went in to safe mode and would not let me rev past 2500 rpms. I did not get a ses light. I shut the car off. Then when I cranked it back up it would start and then die. So i thought it might be the maf sensor. So I disconnected that and then the car would crank up and idle to 2500 rpms. I made it home like that. Then I just know went to reset the computer so i diconnected the negative for awhile and then put it back on went to start the car. it want start. Does anybody have any ideas off what could be wrong.
