Will deleting the 2 cats before the o2's on these cars throw a code?

 

It depends if your SC is OBD1 or OBD2. OBD2 expect to get a CEL for deleted cats, if your pre OBD2(95 and older) you should be OK.

 

This has been covered MANY many times.

Here I searched for "Cat Delete" in the SC section

I even narrowed it down more for you...

Here I searched for "Cat Delete check engine light"

Here is "Cat Delete Problems"

Mmmm as above ^

 

Great answer (edit - fixed your links in post above)

OP (Launch), PLEASE try searching first before posting questions. 99% of the time you can find an instant answer, no waiting.

 

haha i opened each of those links there's nothing there ? Sorry - no matches. Please try some different terms. so much for search

 

Thats odd, they work for me

 

Should work for other folks too now, I fixed them . When you post the search link that works for you because you have the cookie on your PC storing the search criteria, so you can re-execute the search later. Other folks don't have that cookie, so it doesn't link to anything. Got to post the actual search results, which I guessed at and edited / pasted into your post
