With all the talk of removing the AIR tubes and pump, I was wondering if I could do it without throwing a code?
I got rid of my cats when I got the LT's and have the simulators in their place. Will I still throw a code if I take out all the AIR stuff and use block off plates for just the AIR tubes?

Some don't throw a light.. but most do.

ive only thrown the code(P0410)twice in the 5-6000 miles my pump has been off. i think the 01-02 cars dont throw the code as often for some reason

What does the code that it throws when you don't have the pump hooked up say?

LS1 EDIT can delete ses light illumination on whatever codes are deleted. But you wont pass a readiness test (for emissions obd-II tests).

it will throw a code which i believe to be P0140. will usually occur about 100-300 miles after disconnecting the pump from its wiring harness. again as said you can utilize LS1EDIT to delete the code but it will receive a flag from the OBDII emission testing simulation as not being ready.

We don't have any emissions testing here in TN so it's of no concern to me <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> I would however like to get rid or the AIR and EGR possibly without getting LS1Edit, or getting them programed out of the computer. If it's possible to trick the computer like using O2 sims on the rear O2 sensors, I'd like to explore that possibility.

p.s. i threw the code again this morning. and the three times i have thrown the code was while the car was moving.

With EFILive you can look at the status of the readiness tests. All of mine pass everytime and I removed the EGR, rear O2s, and AIR system with LS1edit.
