    eliminating AIR

    When i purchased my 98 T/A it had a magnaflow cat back with the cats deleated. From what i read the AIR system only runs on start up, and it just helps warm up the cats. So, in theory if I do not have any cats could i just remove the entire AIR system?? just to clean up the engine bay?? also, will this throw a SES light when i do remove this?? thanks

    There's a writeup on removing the air system at http://www.ls1camaro.net/sections.ph...ticle&artid=70 if you haven't seen it. Removing it will throw the SES light unless the codes are tuned out. Since you don't have cats (and assuming you're not getting any codes now) there's a possibility the previous owner might have removed the air codes too???? Just for the heck of it I'd pull the "AIR PUMP" fuse and see if you get a light (can't remember exactly but think it should throw code P0412) after a few cold starts. If it comes on it'll go off by itself after replacing it and a few more cold starts. Might tell you if the air codes were deleted.

    That article is alright but it doesn't explain one of the hardest parts, getting that stupid thing back by the firewall out...

    Refer to this one too http://www.ls1tech.com/forums/showthread.php?t=328977

    Check the air pump fuse and relay...then start the car and see if the pump comes on. Could also be the air check valve...driver side.

    that sounds like a short somewhere if you continue to blow fuses

    Could be the pump, or in the wiring somewhere too. Since you just bought it - was if from a dealer? If so I'd call them and see what they say. Laws vary from state to state on emissions related items being compliant when cars are sold. If no warranty/emissions worries I'd consider turning the codes off and/or removing the AIR system.

    Warranty or not they can't sell you a car that isn't emissions compliant. Take it up with them and don't back down, this is a legal matter and they ARE responsible for it.
