You fail emissions test and degrade engine performance despite what some "experts" may say.

Walking skip and stall, was told I let the gas get to low an it sucked in air... how can I get the air out without changing the fuel pump??


if you filled the gas tank after this happened and it still happens then its not an air problem as any air will be expelled shortly after.if it is still happening then you probably have a fuel pump problem.have the fuel pressure checked with a gauge,it should be about 35 lbs if its 5 lbs lower this indicates a pump problem.your symptons do indicate a pump problem.

Check engine light on. the read out was PO411 secondary air injector incorrect flow


P0411 - Secondary Air Injection System Incorrect Flow Detected
On GM cars that still needed Air injection to clean the exhaust they did away with the so called "SMOG" pump, they went to an DC motor driven Air Injection pump, this system is known as the secindary air injection pump, this pump makes a very destictive loud whirling/whinning noise when it kicks on, this happens only on a cold engine, the reason is the fuel injection system is very dirty cold, the pump helps to burn the excess fuel in the exhaust gases. The pump is commanded to run by the computer that operates the whole system, this is the PCM or Powertrain Control Module. The PCM looks for a change in the voltage signal from the Oxygen sensor (O2) to determine if the pump is running. The first thing to do is determine if the pump is working, if it doesn't detect a signal change from the O2 sensor it sets fault code P0411. When the engine is cold do you hear a whirling/whinning noise from uinder the hood? I will bet not, the pumps electric motor is the Achilles Heal of the system and fails on a regular basis, this happens more often in areas tha have heavy rains. Below are the possibilties for the code. The pump is sold as a complete unit, cost is about $300.00, that is just an esitmate as i don't have a new parts book, time to install about 1 hour labor...

Engine light is on and codes say 410 & 491 secondary air pump


Causes
A code P0410 may mean that one or more of the following has happened:
Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump
Blown AIR pump fuse due to freezing up
Possible SolutionsNote:
There is a technical service bulletin (TSB) regarding this code for a number of GM models. The TSB calls for the replacement of the AIR pump and the installation of a new secondary injection hose. The TSB can be found on this ACDelco site.
Additionally, if you simply replace the AIR pump the problem may return again (and again). If you replace the pump, also clean out the hoses and replace the one-way check valve. If this is on a GM model that the TSB applies to, follow those instructions in the link above. In a few cases, people have put a small hole in the rubber cover on the pump which allows any water to drain out.
Also, please note that this may be covered under the emissions warranty on the vehicle. If your vehicle is out of bumper-to-bumper warranty, check if the emissions warranty is still valid!
Replace the AIR pump AND one-way check valve
Test and clean the AIR pump AND test and replace the one-way air check valve
Replace the AIR pump inlet hose
Replace the AIR pump fuse (found under the hood)

What is the air pump for on the 1997 ford 5.8l v8 for and what will happen if it is not hooked up to anything and is bypassed on the surpentine belt?


The air pump injects air into the exhaust manifolds to reduce emissions. If bypassed, the vehicle still runs but you will fail the emissions test and the pump will freeze up if not used. I don't recommend disconnecting anything having to do with the air I breath.

My 1999 Oldsmobile Intrigue's Fuse (AIR PMP-30A) keeps blowing out. What do I do?


What is most likely happening is that the Air Injection Pump, which pumps air into the exhaust system as part of the emission system, has failed. If the electric motor that runs the air pump locks up it will then cause the 30 amp fuse to blow as soon as it is commanded "on" by the engine computer. Usually what happens is that moisture builds up in the pump over time which finally causes it to fail and the only fix it to replace the pump. There were some updated service parts for some of these pumps but I'm not sure if there are any for yours. If you contact a GM parts department witht he LAST 8 digits of your VIN number they should be able to tell you what the pump costs and if there are any updated replacement parts for it. I'm guessing that the "check engine" lamp is probably on at this time also and it's most likely due to the pump not working. Good luck and hope this helps you out some!

Air suspension is not working


It just happened to me. I took it to a spring shop and had the air bags replaced with coil springs. It is an identical fit from a Crown Vic and only cost $200.00 total! Too much can go wrong with other parts of the air suspension. The ride is the same.

Code po410


The P0410 code refers to the emissions system. The AIR pump puts air to the exhaust to lower emissions. It takes in outside air and pumps it through two one-way check valves into each bank of the exhaust.
.
About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.

A code P0410 may mean that one or more of the following has happened:
  • Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump
  • Blown AIR pump fuse due to freezing up
Possible solution:
This may be covered under the emissions warranty on the vehicle. If your vehicle is out of bumper-to-bumper warranty, check if the emissions warranty is still valid!
  • Replace the AIR pump AND one-way check valve
  • Test and clean the AIR pump AND test and replace the one-way air check valve
