AIR System Removal

The Air system and EGR (someone correct me if I'm wrong) is really there for emissions and air quality. It routes some of the hot exhaust back into the engine to prevent gases from being sent into our air. So, if you are in an emission test area... keep the system you'll need it. If not, pull it all out... but you'll have to get a tune to remove the codes...

the 2001-2002 models with the LS6 intake, didn't even have EGR... so it wouldn't make sense for emisions to get too bad without it... it's just a matter of having the right tune... to keep things in check

How does the solenoid on the drivers side under the cowl come off? I can't see it well enough to figure out how to remove it. Everything else looks fairly easy to remove, is there a vacuum line to the solenoid that needs to be plugged?

doing this mod as we speak, when i did my headers i left the egr there bc i didnt have a block off plate i will see if i can make one with what i have.

and i just found that pump lol, and its coming down

lol

We have no emissions test in this state. That is not a concern. I was planning to delete the cats as soon as they act up. I can't even find this AIR pump someone said it was under the driver side headlight in a trap like device but I see absolutely nothing under there. I'm thinking I'll just yank all of this out if I can find it. I'd like to just print out a guide and give it to mechanic if I don't need it. Any suggestions? The install university guide seems to be a bit off base for what I need to do. It's a Ford mechanic so I will need to get it right or I'll have to take it to a Chevy guy who will charge me hundreds of dollars. The Ford guy is family. :\

there, that's what I used to eliminate mine

**NorthwoodDavid** · 11-05-2008, 01:24 PM

Got that sob outta there

now to disconnect the skip shift, if i can find it

lol.

oh i took a pic with my camera phone so ill post it in a bit.

hear you go man, i was in the same boat as you till i was taken out a slight dent and ran into it lol. Its the block thing in the middle of the pic, it has a hose coming from the top of the fender turns into a 90 and goes into it. i think it had another hose but i had already pulled it by the time of the pic.

this pic is with out the inner splash fender(plastic) thing whatever it is. but you can see an opening behind the orange light that is the trap like device, a door lol.

hope that helps

KM02SS - the solenoid bracket may have a 15mm bolt at the back of the engine. Give it a reach around and you'll see. Just loosen the bolt and the bracket will come out... it slips onto the bolt. It's bear to get a wrench on that bolt, but it can be done.

**KM02SS** · 11-06-2008, 05:08 AM

666ws6, thanks for the info. Is that a vacuum line running to the top of the solenoid?

no it's not... the AirPump, doesn't use vacuum to work

**666ws6** · 11-06-2008, 03:20 PM

I wasn't sure what that line ran too. It's some solenoid on top of the driver's side valve cover. Instead of figuring it out, I just plugged it. The car ran fine. Still not sure what that is though.

err, PCV Valve?

**666ws6** · 11-06-2008, 05:41 PM

PCV is pass side at the front by the TB. This is half way back on the driver's side, top of the valve cover. I'll have to look more this weekend. It gets connected to the unit on the far RH side of the picture I posted in #18. I'm not even sure what the heck that module was either.

Seems bad to remove things you aren't sure of, but what the heck...

no, the PCV runs from the Valve cover over TO the TB... to be precise... and if it's halft way, it might be the fuel pressure regulator, if not, then you are just looking at part of the PCV

I have done alot of research but I can't seem to find the answers to my question. I want to remove the AIR system because I'm tired of the DAMN ticking it makes.

Question 1: The line that runs from top of the solenoid to the back of the intake, what is it for/where does it go?

Question 2: Can anyone explain why the SES light comes on when the AIR system is removed? What exactly is the PCM monitoring that sets the SES light?

Question 3: Is there away to fool the PCM in to believing the AIR system is still present? I don't have access to a TUNER and can not delete the codes. Is there away (resistor, simulator, or something) that can be done to prevent the SES light? Emissions is not an issue.

Thanks for anyones help in this matter

Yes, that's a vacuum line.

No, that's not the PCV line running to the throttle body, but it is a vent line. The PCV line is the larger hose below it running to the intake manifold about an inch behind the throttle body.

Here are brief answers to your questions:

1) That is the vacuum line used by the AIR system solenoid--the solenoid operates on vacuum.

2) The PCM controls the operation of the AIR system itself, monitoring each function of the AIR system during its operation by comparing the actual signals received to the range expected. Any signal value outside the expected range throws a DTC and lights the SES light. Removing the AIR system yields a 'zero' value that is obviously outside the expected value range.

3) Yes, but it is much easier to disable the AIR function in the PCM operating system with a tuner or tuning software than to try to simulate the AIR system operation.

Okay thanks but.

I know the line is vacum to the solenoid but where does it attach to the intake manifold????? I know I can plug the line but I had rather plug it at the intake.

On reprograming the PCM I don't have access to a programmer in this area (nortwest tennessee) and don't know of any one with one and no speed shop around. So can the PCM be tricked to prevent the SES light and if so HOW.

Thanks again for everyones help.

it's supposed to attach to the front of the manifold right behind the Throtel to the passanger's side... that's it... no where else...

you need to do what I did... make friends in the area with F-bodys, one of them is bound to have HP Tunner or something, and just give him $100 for the Points needed to work with your car
