What was the code no.?

The only to test them is with a lab scope or good engine capable scanner.

02 sensors can not be cleaned.
Just replace if bad.

Maf sensor can be cleaned with electrical or MAF sensor or carb spray type cleaner.
Just spray resistor and let dry and spray again a couple of times.
Cleaning does it some times and sometimes they have to be repaced to.

For other years that fit check the parts place parts book or salvage yard inter change book.
