thanks for the info, i will give a try. can you rent the pully wrench?

can anyone give me guidance on the removal of a power steering pump on a 90 ls400? pictures or drawings would help or pages out of a manual

The lights don't bother me other than I feel there is a problem. There is a hesitation during acceleration from a stop and sometimes on the open road but that is very rare.

i got two codes, 25 and 26

i have a 1990 LS400. check engine and traction light remain on at all times. car hesitates at stoplights or pulling away from a stop. it is worse when it gets warm outside. i am thinking that it is either the O2 sensors or the mass airflow sensor or possibly both. any guidance?
