Over filling does matter.

 

even though your are over warranty, if it is the dealership fault for setting off the CELs, they can be held responsible to fix the problem....esp if they over filled, but check your levels. Also, what does the other codes stand for? I can't look them up right now

 

I thought I had my account set up to notify me of replies. Guess not.
Here's the rest:

P0455 - EVAP large leak.
P2187 - Upstream O2 not switching
P2195 - Front HO2S signal stuck lean
P1287 - Fuel system too lean at idle

Sounds like O2 sensor to me. Is this something i can do myself? I'm mechanically inclined but have never dealt with this before. Where to look and what it looks like is a mystery to me. I'll start searching the forum for walkthroughs now.
Thanks

 

was it the first or the second o2 sensor?

 

Front o2 sensor is the first one, is your car completely stock? I ask because I have two of those same codes coming up, 2187 and 2195. I'm hoping those are just because of a bad sensor. I have about 57,000 miles on my car and this problem just came up. Also, if you are only a few hundred miles over the warranty or even a thousand, the dealer will most likely do the work under warranty. I had a problem with my sunroof that they fixed with no problems.
