EGR?
I am getting codes 23 and 45 on my 92 LT1. Looking into the various manuals I have says its either the left side oxygen sensor, a vaccuum leak or the EGR going out. Where on that engine is the EGR so I can test it? My books are ambigous - some say here, others say there. Whats the best way to test it? I am thinking this is why I am getting a hi-rpm breakdown and a low-speed surge. This has cause me to have a bit of anguish, especially last night when to happened letting a blown V-6 mustang motor off. :banghead:
