Well it cant be an 88 as that is last year Carburator unless there is a TBI setup out there I do not know about. Mine is an 88 When you car wants to dump fuel the computer has sensed too much AIR via the o2 sensors. Check for vacuum leaks if this came on all of a sudden. Check to make sure the Big tube is tight around the Mass Air Flow sensor or tube to MAP sensor. Make sure the PCV valve to blow apart giving too much air. hmmm Spray around the intake with carb cleaner for any intake leaks ... ( You can use propane )
