Noob apology up front --esp if this is already been addressed. I've looked through the forums but didn't what i'm looking for. OK. So here's the short back story and question (s)
I've recently bought my '04 100 series LC and these two codes came on. (P0420 and P0430. Dealer is willing to throw some money at it to help me get it fixed. The Toyota dealer where it's had most of its work said the previous owner knew about the CAT codes but didn't want to do anything with it as he had just sunk 10K into the brakes, axles, timing belt and more. So, now I've been quoted by them $4500 to replace the CAT and O2 sensors. Another local shop quoted $1800 but with aftermarket parts. questions:
1) I was told that LC's are sensitive to aftermarket CATS. And the engine light may come back on. Does anyone know if this is accurate? And is it still "fixed" even if the light comes on.
2) I've read in a few forums on here that they just found ways to adjust sensors to get light off. As the CAT degrades is it damaging the engine? How urgent is CAT replacement?
Bottom line. I just want to do what is safe, smart and cost efficient
Any and all input is welcome. Let me know if you need more information. Thanks!
