Engine codes 25, 28, 48 on 1994 lexus ls400
hi all,
first post here. i have a 94 ls400 (bought in June, think its before the production change?) that has these lights on. I replaced the ECM last year with a refurbished one, not sure if that's related to these codes.
I brought it into a mechanic specializing in older cars and he was unsure after about 4 hrs of diagnosing the issue. he thought i may have gotten a newer ECM then i needed to, but on the site it said it was for a '94 LS400.
are all these issues connected? should i just replace the rear o2 sensor? its got low mileage (121K sh) so i dunno what to doo
