1999 Oldsmobile Alero GLS 3.4L No Start, Poor Idle Quality, Stall
This car has a whole host of symptoms that occur intermittently. At times it won't start, or dies when running. Sometimes it idles normally, other times it idles above 2500 rpm. It had a whole list of codes when we first got it in, and the ones I listed return...
