Hello,
I just bought this 2002 Cadillac STS, it has 70K. Sometimes when starting it acts like it's having an issue turns over several times, but does start slowly, instead of a quick solid start. Car runs strong after start. Could this be a fuel issue, just bought new fuel filter not knowing cars history, haven't installed yet? Tried a bottle of Lucas fuel treatment in first tank, Ran OBT tool with no codes? Thanks ellis479
