My saturn has trouble starting. Pep Boys said there is a technical information bulletin. I have the paper and it reads: engine coolant temperature sensor related diagnostic trouble code. following conditions and one reads "hard start"
Then it says Replace Engine coolant temperture sensor with new design sensor_ p/n 21025106
Ok, does pep sound like they know cars? The first visit they replaced all the spark plugs for $177. That idea did not work....sounds like a hit and miss type of job, becuase I get a whole new story.
