As stated above I have a 2001 Maxima
130+ miles.

On the way back form my honeymoon we were driving back from Ft. Lauderdale to TN and the issue started.

Power on the low end (below 2500-3000 rpm) was ok, not great.
Above 3000 (if you could get there) was non existent.

So he is a description of the symptoms.

Running in top gear, add a little bit of gas and the motor just falls on it's face. You let totally off the gas and slowly pick it back up and you can regain momentum and speed.

At first there were several codes, fuel too rich, fuel too lean then rear O2 sensor. I cleared the codes in Fla and they never came back on all of the way back to Tennessee.

It reminds me of when you start a motorcycle or weedeater with the choke on it has not warmed up yet, when you give it too much gas it just wants to stall out.

I have had these thoughts of the cause.

Bad fuel filter
Bad fuel pump
Bad mas air flow sensor

Any assistance or thoughts you can think of would be of great help.

Are there any diagnostic tests I can perform

thanks chris

Is there any diagnosis test I can perform with a volt meter or anything to see if it is bad?
