hasn't happened since saturday... do you think if fixed itself?

 

still having this problem, someone suggested that it could be the fuel pressure regulator?> or maf sensor

 

so you checked all the air hoses and vacuum pipes for leaks?? MAF would leave a code also check the pipe from the MAF to the intake for splits, fuel pressure possible and next would be the throttle body like sticking butterfly valve and idle control actuator which is part of the throttle body which might need a clean out, just ideas as to what the problem could be since there were no codes
