so i got the p0420 code again after my first post on this back in sept. i did not remember the make of it but i do not drive the car much at all may have put 200 miles on it since then. and now in the last 2 days i returned back to work and now i got the code again. so i must have got the wrong one, seems it shout not have went out this fast.

so rock auto has them for like 50.00 or might i want to vist advance auto and pay 80.00 but then if it fails i may have a warranty? or what parts store offers a warranty.

last time i went thru the 02 sensor issues was on a 95 lebaron and i spent hundreds trying t get that one corrected and the last one came from the dealer and they did not stand behind it either. if that is the case and i get another one and i get the code again i just put tape over the light and forget it. tired of all the money on stupid stuff.
