We have a 1990 Cutlass Ciera that blew out the O2 sensor and went into limp home mode. The sensor physically blew out from rust.
So I put a new Bosch one in and at about 500 km later, it starts acting exactly the same, with a miss all the way up the throttle and basically no top gear or bad shakes in top gear, just like last time.
It also dropped to 18 mph highway from over 30 again.
I decided to get the codes to see if maybe something else has gone bad, and after reading '12' three times, no more codes came up.
The question is should the bad O2 give a code and/or any other suggestions for a no code miss?
The engine has new plug wires also and the fluids are all up.
Thanks,
Mike
