i think i found the solution and that is the bank 1 is not the knock sensors but its the oxygen sensor. the cats were deleted . so it has to be the front o2 sens

You didn't bother to even check what the codes were?

Deleting the cats will not affect the front 02 sensor only the rears. The rears are either bank 1 sensor 2 or bank 2 sensor 2. What is the code example- P0315 ( Crankshaft positioning sensor variation not learned)

Auto Zone etc. should they tell the code # or just what is wrong

All Advance said was that it a ' bank 1 ' or should i go some where else ?

Advance reads the codes and then gets a print out that lists the code and a description. Make them give you the paper so you know exactly.

I love it when people read a code, then just start replacing parts without researching or troubleshooting anything. There are tests that should be done after you read the code. Once you have the DTC, you know which tests to do.

Yep. Some of them are pretty serious.

yeah i got 2 codes now p0327 and p0420
