Hey all, as I bring this '00 Maxima back to life, I seem to have a problem with fuel delivery. She has 200k miles and sat for about a year.

This car will cough and sputter if I push on the gas pedal too hard. It seems to happen around 2,000 RPM.

I've cleaned the throttle body, sprayed cleaner inside the IACV (couldn't unscrew the 4 screws to get inside), and replaced the MAF with a unit from Courtesy Nissan out of Texas.

When I replaced the MAF, the car drove fine for about 2 days. She would rev smoothly all the way to 6,000 RPM.

But today, while driving back to work, the car would almost die if I pushed on the gas pedal about an inch or so. If I kept pressure off the pedal and moved it less than an inch, the car would drive fine.

Any ideas? Could the computer be going bad?

Thanks for the help!

 

alternator

 

I've replaced the MAF with one from Courtesy Nissan and she has a brand new battery.

 

Still...
What about the camshaft sensors?

 

haven't checked that... but the car sat for a while, perhaps it's coated in gunk. I'll look into it.

 

definitely sounds like alternator going out, i had a bad maf once in my old 96 maxima, car would drive fine but die when i came to a complete stop, in my 02 max when my maf went bad car wouldnt rev pass 2000 rpm
