SILVER Star
I have a 2001 LX470 that is pretty much stock right now. Almost 85K miles...previous owner drove mostly commuting in Los Angeles before I bought it. I have been tracking my gas mileage for the last two years since I bought it. My best was 18.6 mpg with non-ethanol gas and my worst was 13.4 doing lots of short commuting around town.
This last fill up this morning netted me horrible gas mileage...8.7mpg. All the driving on this tank was commuting around town. I don't sense any change in the power of the LX...seems to rev consistently and with no real deviation in RPM's since I bought it. No fuel smells in the garage...
I have replaced both front O2 sensors in 2010...otherwise, nothing done to the exhaust or intake systems. Stock tires for now, no additions in terms of bumpers, etc. Actually, the only thing I did in the last few weeks on the truck was remove the battery to replace the headlight bulbs.
The 90K service has not been done as I was planning on tackling that this summer. I searched through the forum and found that it may be the catalytic converter. Before I go down that road, I wanted to get some feedback from the experts here. Any specific tests I should run? Any thoughts on what the issue could be?
