I got this off a slcsr.com and was wondering what you guys think...sound like MAF is going out but.....I am usually always wrong this is what he wrote...

ok my roommate has a 2000 maxima 5sp, his car is throwing code 171 which i know is 1st bank running lean but does anyone know what the most likley culprit is? i thought is was the mass air so i cleaned it with brake cleaner and that didn't help (i was told it was a common problem with the max.) so what happens is it idles normally and runs great until wide open throttle and about4k-5k then pulls hard after that but right there between those rpm's it almost feels like a fuel cut. only mods are a cold air and a cat back thanks

 

Dude i really seriously hope you DID NOT spray Brake Cleaner Into the Mass Air Flow Sensor, im almost positive your going to need a new MAF now.....for electric parts theres this stuff called ELECTRIC PARTS CLEANER , never use carb cleaner, brake cleaner or whatever on elec. parts

My 2000 Max had the same CEL error and had poor pick up at lower RPMs. I repalced the MAF and had the computer updated with the new code for the new style MAF. Car runs like new again.
