I replaced the ecu today & havent had a problem since,
but now my car goes up & down,up & down,about 3-2000 rpm,
then it quits,weird,
I disconnected the battery when changing ecu's,
it usally does this when I first change them,then sooner or later it quits,
I guess its just the motor getting use to the ecu,
thanks to everyone who helped out,
AF has always been like that.
