2002 STS

Asked by Feb 07, 2011 at 07:05 PM about the Cadillac STS

Question type: Maintenance & Repair

Engine light came on, took it to a shop that put it on the computer and they said I need new plugs, gas filter and rear O2 sensor.  He wants to charge me 189.00 for the part, they are cheaper online but I need to know how many prongs the current one has so I can order.  Where would I find that information online?  Thanks!!
