Subject: Failed Smog....UPDATED!!! PASSED SMOG!!! by bogus on 2014/10/10 15:59:53 Rather surprising, really... 92 Coupe, LT1 (from a 96), new California legal Magnaflow cats, LTCC. It ran real lean at 25 MPH. The NoX went nuts... went from 300 and something @ 15 MPH to 650 at 25 MPH. The Lambda calculator indicates lean. I am thinking: 1. Bad vacuum to the EGR 2. The air pump, being disconnected, isn't helping 3. Loose O2 sensors |
