that is correct. find a shop that knows that. but running old cars, no shop has these tools.!!! (no TECH1, and if had one, it be like junk now, this old, and dead)
that is why when owning old cars the owner needs to be more self sufficient.
Even if all you do is , have the tool in hand and show your mechanic the methods of 1989 (circa) (look here, see me scan my car....)
look, here mr, mech,, see my 02 go nuts at idle. can you cure that ? (you to him)
see, now you are part of the path to solving problems, not just wishing....
i forget, did you look under the exhaust manifold shield for this?>

the crack changes sizes (sucks more oxygen) under weird conditions.
crack might open more at idle (cooler) and close at cruise. and not leak at all, hotter. (had 2 do that, and seen many others same)
this is why savvy mech, drive and log sensor data.. to learn what REALLY is happening.... (or spend forever guessing or saying car is a LEMON)
as I said , you can not work blind
nothing more needs be said, about working blind.
one can back probe the ecu to see if some pins are wrong.
best is to unbolt ecu , let it hang so pins are easy to reach.
seat out.
and idle hot engine and probe.
scanning is 10x more easy but this would find , pins wrong. in wrong state into ECU.
