Hey guys so i recently posted about my MAF sensor. I cleaned it and tried to clear the codes but it wouldnt let me so im guessing its not my MAF. Here are the codes, can someone help me diagnose what it is.
The only one im worried about is "Diagnosis of tumble flap 'Intake manifold' : Short or open circuit in sensor lines / Mechanical fault of one actuating lever / Sensor faulty, replace sensor." Is it just a sensor or am i going to have to replace my entire intake manifold.
Thanks rudeney, i found out what the problem was and i feel very stupid. My engine cover bracket was bent in causing it to not sit flush with the MAF sensor. It caused all the false codes above. I fixed the bracket and the car runs like a champ. I did take my MAF off and cleaned it. I now have only 1 code. Instead of the 4. Its the p0175 (bank 2 running rich) I've been told all i have to do is complete a drive cycle and the code will delete itself. I actually took it to autozone and they tried to delete the code 3 seperate times . It wouldnt delete therefore my CEL is still on. But the car runs great. Im pretty sure i just have to do a drive cycle, im pretty sure it wouldnt delete itself because the car wants me to do a cycle ( i also disconnected the battery) btw the p0175 is the only code i have. Im guessing its going to go off by itself (praying). Heres a picture of my stupidity lmao
That very well may fix the mixture codes, but the tumble flap code will likely return. You can visually check that actuator to see if it's broken. It won't cause any serious problems, but you will get intermittent codes and slightly reduced performance.

will the tumble flap code cause my CEL to come on? Because i think you are right about the code coming back.. When i got my altenator replaced my mechanic told me a code about having to do with my throttle body but he told me not to worry unless my CEL started flashing. (It never did) im hoping tomorrow to do a drive cycle and hopfully my CEL turns off. Thank yiu again for the reply. I thought it was pretty crazy how that bracket caused my car to run like crap, i couldnt even gun the car, the rpms would barely move when i pressed on the gas, but since fixing tje bracket making the hood cover correctly seal with the MAF sensor the car is back to full throttle response!
If you put some dielectric grease, or Vaseline will do, on the rubber/polycarb the clips fit over, the cover will go on more easily and you're less likely to bend the clips.

thanks for the advice! Im definetly going to do that
You can also do the same for the rubber fitting on the cover that goes over the MAF/intake. When seated, that sealing/rubber piece is below the opening of the MAF, so there is no danger (even if a bit was ingested it would be vaporized instantly). No need to put a lot on either location. Just put a dab between your thumb and a finger and run your finger over the surfaces. They will get shiny. And that is all you need. Remove any excess just from a neatness perspective. You will then be able to remove and install the cover without having to jerk on it or pound on it.

The tumble flap code can sometimes trigger an MIL, but often does not.

luckily i just completed my drive cycle and CEL automaticly turned off. I went and i have 0 codes so hopefully the tumble flap doesnt come back on. I really dont feel like checking myself so ill just scan my car in a week or 2 and see if it ever shows up. Thanks again for all you guys responding so quickly and informative.
It's pretty easy to check the lever visually. Just remove the engine cover and look at the front of the intake manifold where the three vacuum actuators are located. The middle one actuates the tumble flap lever. Visually follow its control rod down to where it attaches to a ball join on the lever. Either the rod or the lever will likely be broken. Refer to that link I posted above from Pelican for pics of what you are looking for.
