Hello everybody I have a 2006 Honda Accord Ex 2.4L 4 cylinders with 100,100 miles on it. The problem I have right now is that I start noticing my RPM struggles to past 3000 and that’s with my foot all the way down on the pedal. My first thought it would be the mass airflow sensor so I first clean it and I still have the problem then I went to Autozone to buy a new mass air flow sensor. I went out to test it and It work but the problem came back it and worse it gave me check engine light and the code was P0113 so I put back the OEM sensor and the check engine light was gone. Then I went change the EGR valve which to be honest it did looked like it needed to be change cause it was super dirty. Still I have the same problem although it look like it help a little bit maybe I’m wrong and my eyes playing tricks on me. I don’t want to buy the wrong part and keep guessing. Anybody have a clue what could it be? By the way my transmission(automatic) is fine and smooth.

Actually it doesn’t look like that. It look like this, connected to the air filter box. The one at autozone I bought gave me that check engine light code but when I put back the OEM back my check engine light disappeared. Another thing to is my throttle body is brand new that I put but unfortunately I’m still having the problem. 😕
