Air flow meter is the wrong one

I am not sure I understand what you are looking for. If the engine is cutting off at 4500 RPM have you pulled codes or replaced any parts? Why do you feel that the air flow meter is incorrect?

If we haven't pulled codes, let's start there and see what comes back. Then can you give a little more detail on what you are dealing with? Does it cut off every time it reaches 4500 RPM or does it only do it sometimes?

Thanks for the question. I see that you had another similar question. Please respond to this one as it is more clear as to what the issue is.

This is possible but I would expect it to set a code. Is the check engine light on? Have you checked for codes?

Next can you provide the different part numbers so that we can try to figure out if the sensors are different? It is possible that the sensors are different part numbers but they operate the same so that would not be the cause.

Did this issue start right after you replaced it? Do you have the original sensor? Can you install that one back in the engine and see if the stalling stops even if there was another with the other sensor?

Let us know. Thanks
