I have a 96 maxima auto n lately just feels like there is nt as much power as there used to be I used to slam my foot down n it would light the tires up now I know I have a bad knock sencor n maf but they been like that for while I'm nt sure if those could do it what do u guys think

 

I would definitely fix those ASAP. These are definitely robbing you of some power not to mention mpg as well. Fix them and see how she runs.

 

Will do that another thing is there an after market knock sencor or maf

 

I got my knock sensor off ebay for $7 lol. It works fine. Now for the maf I don't know if I'd trust an ebay one. I'd pick up a used Oem one and just clean it with maf spray real good.

 

I was just looking on ebay for a maf I might have a buddie with one from a 99 maxima thanks for all the help

 

No problem. See how it runs after that.

 

Yeah I have the same problem with my 97. Except I only have a bad egr sensor?

 

EGR sensors only really affect Gas Milage, because the EGR system takes your exhaust from your third piston, pipes it around for a while and reintroduces it into your air flow to help save gas. If the sensors are going bad you are probably getting crappy gas milage only. Shouldn't affect power at all

 

Most likely The EGR guide tube is blocked with carbon build up like mine was. common thing with the EGR, try taking it off and cleaning it.

Oh I get it......he should check his muffler bearings too.......

 

Yes I knew all of that except for the bad gas mileage part, that's why I put a question mark at the end of my sentence because that shouldn't affect anything. I was just saying that's all. Have as far as cel codes go.

If you haven't ever changed your O2 sensors, change 'em. Just the primary O2s. They get tired and don't throw codes, and when they're tired your car acts sluggish.

 

Well droped some cash in her gt a maf for fweeeeeee from my body had it looked at n it works great cleaned in all perty n gt the knock sensor as well I gotta say she feels better than when I first bought her 5 years ago thanks for all the help guys guess it was a plus becoming a member on this site

 

Egr introduces inert exhaust gasses to lower combustion temps and nox emmissions, not for economy. An egr valve hanging open woild cause roigh running and stalling.

 

Knock sensor was the most noticeable "mod" I have ever done.

 

Don't forget the blinker fluid

Make sure everything is fixed on the car, and maybe seafoam will help
