So replacing the MAP sensor didn't help the reduced engine message, but replacing the fuel injector did help the problem? I having similar problem with my 12 Malibu. I do also have some obd codes with an engine light.
Is your malibu sending codes for ignition? I know mine was telling me Cylinder 1 was misfiring. I changed out spark plug, but I'm gonna replace coils, and plugs for all 4. Mass Airflow sensor is also on my list.
Manuel Guevara nope!! replacing the injectors did. now I'll try and tackle the exhaust manifold...I'm getting fumes in the inside, and it seems they're notorious for getting cracks in them
lol I came here for the MAP info but I can agree with you, I think my exhaust manifold has a crack somewhere too as I think I can both hear it on startup and smell a bit of an exhaust odor near the front of the car. Nothing in the cab yet thank goodness.
Thank you for sharing your experience, it's been very helpful
This was very helpful Thank you so much for the video been looking all over

FYI MAP= Manifold Absolute Pressure
Lol I almost made the same comment 😅😅
It would have been most helpful if you showed from beginning to end
Who the hell does this help you didn’t do sht
You got rip off if you bought it for $70. Cuz I'm a mechanic and ik 100% they do not coast that any where. Even at dealership.
They do at autozone but ordered mine for 20 on amazon

it didn't help mine. some people had reported it did. my code went away after I did the injectors

@@nasrillukty just google mass airflow sensor for Malibu, your year model and engine size, and you'll get the part number.
Just called auto zone its 43.99
part is 30 bucks at any gm dealer.
manifold absolute pressure sensor....
Michael Ramm yep... you're right.
Michael Ramm did that fix the shaking and the reduced power and all that?
