This thread has a link to the ss handbook which tells you how to disable it along with a wealth of other information. To delete it you just yank the air pump and all the sh*t that runs to and from it out after you disable it. I don't think you're supposed to yank out the electric wires that run to it though, just zip tie them off to something. Idk.. someone back me up.. oh.. and use the search function.. type in air pump.. and you can find other threads about this.. and you can find the size plug you will need to plug your manifold if you decide to delete the air pump instead of just disabling it.

ledsled has it right. just unplug it and tie the connector outta the way. when you remove the piping they will be tack welded or rivited or something to the bracket for the alternator (ithink) just wiggle and it will pop off. what i did was take the driverside and bend the pipe back and forth until it snapped in half under the front of the engine, (cause i couldnt get it ALL out in one peice)pulled out the driver side, then worked the passenger side out. but BE CAREFULL!!! not to cut or pinch and damage the passenger plug wires that run under the alt. mines a 95 so no need to reprogram the pcm. leave the fuse in cause it runs the hood light also

its easy

also.... i pulled mine off down to the manifold itself. so i used two oil pan plugs for a 2000 dodge dakota from napa to plug it up. fit perfect. i know there are other options out there (maybe cheaper too) but thats just what i found at the time.
goodluck

The A.I.R Pump disable process is listed here in the tech section of forum at this link:
http://www.impalassforum.com/tech/en...p/air_pump.htm

Below are pics of the AIR pump deleted, and the Oil drain plug I used to cap off the exhaust
manifolds plug for my 1995 LT1. The 94 and Early 95's are the same size, The later 95's and 96 Models
are different and use a 5/8" Flare Cap nut to plug the manifolds. These can be found at Lowes or
Home depot. Determine which manifold type you have Here (Husskers pics)
How to Delete your AIR Pump

The 96 model AIR Pump delete also requires a reprogram (OBD-II) Also, DONT use the
paper gasket that comes with the drain plug on the exhaust! Go to your local hardware store
and get a "Thin" copper or metal gasket for the setup (Pic). I Highly suggest that when your
preparing to do this removal project, lightly wire brush off the threads of the AIR Pump tubes that
go into the manifolds, Get the manifolds "Warm" (Not blistering HOT), then spray down the
threads/AIR Tube connector with PB-Blaster and let it set for an Hr, repeat the Heat/PB Blaster 1 more time.
Make sure you have the Correct size wrench for this Job!!! It is recommended that you
Use a " 6-Point Line" wrench for this Job! You may only get 1 decent shot at getting the rusted
tube fittings loose and you dont want to strip the heads in the process. Go easy and they will
come loose and out. Tighten the manifold plugs down decent but DONT over-tighten them!

Well, Clicking on the link already provided in this thread (What it's there for) would explain the reason(s) for the fix .
Here it is again.
http://www.impalassforum.com/tech/en...p/air_pump.htm

DTC = Diagnostic Trouble Code(s)


Technical - Water in AIR Pump and/or DTC P0410, P0412, P0415, P0416, P0100, P0101, P0102 or DTC 48 (AIR System Disable Procedure) #01-06-04-011

Water in AIR Pump and/or DTC P0410, P0412, P0415, P0416, P0100, P0101, P0102 or DTC 48 (AIR System Disable Procedure)
1995-1996 Buick Roadmaster
1995-1996 Cadillac Fleetwood
1995-1996 Chevrolet Caprice, Impala SS
with 4.3L or 5.7L Engine (VINs W, P -- RPOs L99, LT1)
Condition
  • Some customers may comment of a hesitation during heavy/full throttle acceleration.
  • A 1996 vehicle may also set any of the following DTCs:
    • P0410
    • P0412
    • P1415
    • P1416
    • P0100
    • P0101
    • P0102
  • A 1995 vehicle may set a DTC 48.
  • There will also be evidence of water in the AIR pump.
Cause

Under high engine speed and load conditions, hot exhaust gasses may leak past the air check valves. As the exhaust gasses in the air tube cool, water vapors collect into the AIR pump. As the vehicle is driven, condensation from the AIR pump may come into contact with the Mass Airflow Sensor through the AIR inlet hose. This condition may cause a hesitation on acceleration and may also set the DTCs.
Correction

To correct this condition, a Secondary AIR Injection Pump disable procedure has been developed. (It has been determined that the Secondary AIR Injection system is not required to meet emission requirements for these vehicles only.) In other words, you can remove the AIR System all together and on a 96 model B-Bodys, A GM Dealer will reprogram your PCM to delete the AIR System out of it per the TSB (Technical service bulletin) #01-06-04-011. Just give them that number if you still have the AIR system in your car and want to get rid of it. There also a Sticker they put on the Radiator support of the car for those that have to do Emissions testing that says it's been legally removed.
