you know.....Now that I look at it these are the exact same codes that I got just recently....I took it to my personal machanic....and he asked me if my Fuel level gague was working....and it was it was working fine. so he just reset the code. I think it happened when the stupid dealer where i bought it from, filled up my car with 87 octane(iv only had this SVT for 3 months) in stead of 91....i got such crappy millage.....well my gague works fine.
Just to let you know, code 460 will not set off your check engine light.....But i find it weriod that the exact same codes that I have would appear in your car too....maybe the bad gas affected an o2 sensor. But im waiting for it to show up again.....If the same codes reappear then i know that there related.
Save your money for now...Let my car be the gunnie pig so i can tell you whats wrong and you don;t spend a crap of money on fixing problems that don;t exist.
PM me if you want to Keep in touch on this subject.
