my air pump maybe going out cause when the car has been sitting for about 45min to a hour after its been ran on start up it sounds like a spaceship or something for a min before the sound goes away. is the air pump needed on the cars? can i delete it or will it mess up my egr system?

delete both and turn off all corresponding codes. but no it wont mess up egr they are 2 different things....both of them are worthless

tho i see you are living in the wonderful land of california.....so this option may not be possible due to the inspections you must suffer thru..id get block of plates and sandwich them between the air tubes on the manifolds and egr then turn the codes off that way everything appears to be "tree friendly"

you can yank the 30a fuse for the air pump, no need to block off the tubes you have check valves.

My check valves went to ****...the block offs would be the next best option there's no chance they will leak unlike the valves...the fuse would be easiest...

wouldn't you still need to have it tuned out so it doesn't throw a code?

I removed my air pump an hour ago .... my egr is disabled but still not mechanically removed .... I got a SES CODE after the air pump removal thou =(

Air pump is to preheat the cats, nothing to do with the EGR

goes disabling the egr creat any time of power since hot exhaust gases arent being put back into the engine or no? i have the stock ls1 manifold but dont have the money for an ls6 at the time so i just cut the down tube to make it flush with the top of my manifold

I feel u but mentioned to clarify .... it needs to be tuned out period

We're in California man, you gotta leave that stuff intact. Even if you were to tune the stuff out, wouldn't the smog machine notice that was done?
