Thanks Eric. Seems to be the norm from manufacturers - no rebuildable/replaceable pieces on parts. Buying complete replacements is causing sky-high repairs and angry customers. You end up doing more explaining than fixing, sheesh!

I remember back in the 80's I had one of those on my old Firebird. I didn't realize they were back again. Sounds like a vacuum cleaner lol. I didn't expect it to flow that much air from the sound of it. Thanks for the informative video.

GM, payin' the bills, as usual! LOL

That Chevelle in the background was close to GM's peak - all downhill from '73 on. :(

[johnbowers]

Thanks Eric now I can fix my car you are always helpful

[billscott]

Thank. You Eric. I own 2012 Chevy Malibu with 2.4 liter. I learn more about my engine.

Another great video, Eric. Very rare to see you use your digital test light. Good to see a use for it. Sure wish those scan tools were more affordable but that's how they keep you in business. Thanks for throwing out some quick ideas on how to get some results without one. Makes for a super video!

I'm glad my Malibu is an 08 and doesn't have that stupid system on it! I noticed in the video that Malibu had new variable timing solenoid valves

[ThecardoctorTV]

Eric, how do you keep your hands so soft and supple? Any product that you recommend for keeping them from looking like "mans hands"? Oh, by the way. Nice video as always mate!

[sublyrikalproductions]

My secondary air injector itself is bad, i cant find where its located anywhere online! Such a pain. If you have time could you please explain where it is so i can replace it? Would be greatly appreciated. Thanks!

Good job eric always learn a new fix with you but where is the boss?

[farmallc]

Erik did you make video on that 67 on lift ? I built 66 drag car.

[RLGERHART]

I have a 2010 Malibu with the 2.4L, I have a this brief noise on cold starts. After research I've learned that it is an air pump (I'm assuming it's the AIS) that is required for emissions in some states. In your opinion does this sound accurate to you and if so is there a way to quiet it down? Thank you in advance.

[alantschirner]

Thanks for the straight poop on the bow tie. Can't wait for your next installment.

[eldoradony]

What's doing with the 67 Chevelle that's been on the lift for the last couple of weeks?

[chargerforever]

Good fix to learn those 2.4s are getting popular

[gssracing]

That sure is a fancy scope on a rope youre using there LOL I like it Thanks for all your awesome videos

[cbobcbob]

thanks....Where did you get the small yellow test  lead you used in testing and cost ?....thanks ....bob

[emtscythe]

Awesome as always. You could also use a relay jumper like the Lisle set to turn the pump on. Yes these air pump systems are ridiculous. I deleted the one on my sons 93 F150. Yes it's a Ford but it was his Grandfathers truck ( mothers side, my dad would never drive a Ford lol ). I may have to pick up a digital test light just because.

Thumbs up great video. Had to watch it three times to understand it all. Some advanced stuff at 5:39, plugging test light reduced voltage into the signal return wire to confirm circuit is good with the help of a scanner. If I accidentally sent 12 volts into the signal wire using a Powerprobe, would I blow the pcm?

got gas, parked the car in some gravel, started it up and got this code.

an 09 cobalt base xfe model, opened the lower pump seemed fine. then opened that rear pump valve and lots of carbon. did some diesel injection. on first start up i can hear one of the pumps.

does the diaphram rip? or does it just get stuck open and wedges itself from moving? also there is a button on the unit, i dont know what it does or if its just a one way valve. can you cut the old unit in half?

symptoms are choppy drive at steady throttle
