Verified the Code 91 on KOER today in the 88.
Going to take a stab at replacing both original O2 sensors since I have new ones on hand.
Advice on removing the old ones (still running stock manifolds)?
Use the O2 sensor socket or snip the wires and use a regular socket?
Engine hot or cold?
Use heat (acetylene available) or not?
I have done O2’s on other cars before but I know this one is going to be a pain since they are original and this car has seen many decades of salt.
