Dan B Posted August 15, 2010 Share Posted August 15, 2010 i can only comment on my districts emissions rules, but in all of my LT1 cars i passed emissions without the airpump, and with the egr tubes sealed off at the exhaust. Are you in california? and are you talking about ref station passing or just a regular tailpipe test? Quote Link to comment Share on other sites More sharing options...

gvincent Posted September 9, 2010 Share Posted September 9, 2010 I removed the Air pump and EGR only. Since I already had the stock 280Z EVAP and vapor return line going back to the fuel tank I kept the EVAP on the intake manifold and just ran a new hose to the 280Z eVAP canister on the passenger side front fender. It was easier than dropping the tank and plugging the EVAP line. Quote Link to comment Share on other sites More sharing options...
