Gas milage and performance of wife's 1995 945T has been going downhill for past several weeks. O2 sensor is only cycling every 8-10 seconds or so when lead is backprobed, looks like I need a new one. This particular year and model has an EGR valve, and local sources for this O2 sensor range from $220 at dealer to $195 at NAPA. IPD has one for $165. Anyone have any ideas on a cheaper source? Will the O2 sensor for an older model b230ft (1991-1993) work just as well? They seem to be cheaper (Borton has one for $123). Is it just me, or has the price of O2 sensors gone up in the past 6 or 8 months?
What about the universal 3-wire? It seems like those are really cheap if you are willing to do some splicing. If I can get a decent deal on one that doesn't need to be spliced, that would be preferable.
