Possesed VehiCROSS

Tone,
I assume you saw that in Dr David's post, yes you are correct - I changed to the oiled K&N filter and removed the screen. This is what I attributed the check engine light to initially, but as I said - it only happens in her end of town - that's the part that has me puzzled. This has been going on for a little over a month and has only happened one time elsewhere, but everytime I go there. There is no significant difference in elevation, she doesn't live on a dirt road or something that might be clogging things up. Maybe it is the mods, but I can't understand why only in one part of town. As I said in the other post, I guess I'll take it to the dealer and let them play R&R (remove and replace) until they find the problem. Another thing I failed to mention is that it seems the old girl (the VX, not my girlfriend) has been a little more thristy lately. On my fill-up yesterday, I did the math and calculated that I got 13.5 miles per gallon. I'm not a granny driver, but I don't drive it like a race car either. Based on comments I've seen here, that seems a little excessive. I've never gotten over 16mpg - at least not the times I've calculated it - but it's not been this low before to my knowledge. I did recently change to larger tires which are slightly larger in diameter (about 1/2" I believe), so this has a little to do with the mpg, I'm sure. Anyway, I'll be taking her in next week to see if they can figure it out.

Having just gone through the P0171 code with my old Geo tracker, this code is usually due to a vacuum leak somewhere. Check the hoses and especially the EGR valve diaphragm and the charcoal canister. Even a small leak will set this code. Another cause is a bad O2 sensor.

Have you been using an injector cleaner lately? Since your code came up as "lean" you may have the same trouble as a few others where #1 bank has foulded or clogged. I always run injector cleaner through about every three months and make sure my gas cap is screwed on tight(this also will give you a code reading). Also check for vacuum leaks near the top of the engine.
Good luck...John
