    Just installed LTs w/ EGR delete

    Just installed a set of Pacesetter LTs and got rid of all the egr crap... There is one (maybe 2) piece(S) of like 1" tubing on both sides of the intake that were hooked up to the system that are blowing air when the car is on, what gives?

    The tubing sounds like the air pump hook ups and thats why its blowing air. You can remove the air pump and have the codes turned off.

    Yeah, sounds like the AIR hoses that would go into the manifolds. They are there to pump fresh air into the exhaust stream to help the cats heat up quicker and to reduce the percentage of oxides in the exhaust. They are not part of the EGR hookup. You can pull the fuse or unplug the AIR pump but I think you need to have a tune to delete the codes like the EGR. I got the full emission's headers so I can leave everything hooked up and went with dual 3" cats too. NJ is tough on inspection and there's really no reason to remove the stuff if the car is a daily driver.

    if you unplug the AIR fuse, will the codes still show up??? or do you need to tune them out?

    I removed the EGR & AIR systems completely.
    For the EGR, remove the pump and tubings all at once, you will need to get a freeze plug to install on the intake manifold, I think it was 1 3/8.
    For the AIR, removed the pump which is accessible underneath in front of the drivers side tire. Remove the tubings as well, one bolt holding the little pump in on the back of the motor. Be sure to plug the vaccum hose, your good to go.
    Be sure to get a plug for your lid too so you will not lose any air thru there.
    Saves about 10-12 lbs for all that crap and we really don't need it down here in Fl.
    I am having my tuned out as well as the rear O2's

    if you pull off the whole AIR system, and then pull fuse, will the check engine lite stay on?
