Recently, had a friend swap engines on my 94, the cooling fan stopped working so I replaced it with a aftermarket one. I passed emissions with flying colors even with a check engine light. I pulled the codes and I get code 172,
which states O2 sensor indicates lean bank # 1. I also get code 538(I don't think I should worry about that) With the key on engine off I get a code 563
High speed fan failure(that's why I put an aftermarket in.
So, Question 1:
How can I eliminate the code for the fan?
Question 2:
Where should I start for code 172?
Could it be a dirty injector?
Car runs very good and has power.
Any info would be appreciated
Thanks,
Brian
