service engine soon light at 80mph+ - 12/18/2007 7:16:56 PM    non blazing 4x4   Posts: 25 Joined: 7/31/2007 Status: offline Today i was driving on an open country road and decides to open my baby up.  I stomped it a 55mph and about 5 mins later i hit 80mph+ when my girl friend informed me that my s.e.s light was blinking.  Well i left off and when it slowed down the light stoped abd stayed off.  I droped my girl friend off at her house and on the they home i hit the same strech of road and hit it again.  Same thing.  I seems like when i get about 3500k to 4000k in 4th(4 speed auto) the light started blinking.  I donw know if it was engine speed or actual speed that set it off.  Drove it home and it never came on.  Even at 70.  Seems it may just be under hard accerlation.  Any help on this would be great.  Truck runs and drives fine i just dont want to damage it.
