Hi, my friend has a 2k1 maxima automagic, he bought a ebay intake
http://cgi.ebay.com/ebaymotors/ws/eB...tem=7956406743
and after he installed it, the car runs like shhit. He says he has no power. Car hesitates . What could it be??

 

It could be the maf.

 

u loose low end torque with Cold air intakes...
make sure all his hoses are connected tightly and everything is snug..

 

how much low end will you lose? im about to install my berk with apexi..will it be something really noticible?

 

Don't know exactly how much, I don't think there's any way to really know...

I lost some low end with my Berk/K&N... its noticeable to me although it feels fine once you're over 3000-3500 rpms.... but the addition of a y-pipe regained some of that... plus more elsewhere...

 

That's more than just the usual low-end loss with intakes.... possibly a MAF issue, like someone already said....

 

so after i pick up the cattman y all the way back to the muffler i should be fine again right?

 

Well, depends on what ya call "fine again"... it doesn't feel quite as quick from a stop as it used to, but once ya hit the higher RPM ranges it really pulls... I do go through the gears faster now, so I'd think that its definitely added some over the entire powerband....

Just get it dynoed before the intake, with the intake, and with the intake/y/cat-back and look at the plots... that's the best way to really know... and I'm sure the rest of the .Org would love that contribution too, seeing how that's always discussed around here....

 

soudns good to me...im running an auto tho so maybe the numbers will be a little different...either way one more ? for you...should i replace the cat with a hi flo one or the straight pipe on custom maxima or just leave it alone...i dont kno what the differences or advantages would be between the 2...i wouldnt want the straight pipe to ruin the sound of the exhaust tho...thanks

 

thanks guys for the quick response, we will take a look at it. I have PRCAI on my 98, but i'm 5spd so i never actually felt anything like him.

 

From looking at the picture of the intake I could not see where the MAF should be plugged into, so you are probably right Trance.

Why would your buddy buy an intake from someone that claims that the 02-03 Maxima's have 3.0L engines?

 

anyway to test the MAF? A bad MAF will throw a CEL ??

 

sometimes it will. mine did not until i changed the plugs. don't replace the whole maf. just buy the sensor. sensors are 70 bucks

 

See if you can find another 00-01 Max that runs fine and swap MAFs as a test....

 

Junk the POS Ebay intake and get Berk. If your MAF is blown get a new one.

 

I felt the same way when I put on my injen... you will not notice an intake on a maxima like you would on an accord.

 

Let me just set something straight:

Even though you may lose a little bit of low-end torque with an intake, you shouldn't lose so much that your Maxima "runs like shhit" and "has no power." After I installed my Berk intake, I was still able to shred rubber without even flooring it, and the car definitely didn't "hesitate" to do anything like your buddy's car.

I know your buddy has the VQ30DE, and I have the VQ35DE, but even the VQ30 should still feel powerful after an intake installation. Maybe during the installation, the MAF was damaged or something, but if he did everything right, his car shouldn't suddenly feel crappy.

 

i think it's the MAF. my car came back from a tranny shop after putting in a clutch and they have to take the intake pipe and icebox out to get to the tranny. after getting my car back a week later... my car felt like shhit and still does. people on the org is telling me it's the MAF and also they recommend to clean out the throttle body. my car is REALLY slow right now and when step on it it sounds like i have a weak intake (hear some roaring) but i think because the MAF isn't giving sufficient numbers for the ECU.

 

lol, i got the same intake without the cool Tokyo Engine sticker for $35 shipped. that sticker will make your engine compartment smell like a rice bowl

 

I've had the Berk on for over a year now, Jersey, and haven't especially noticed low-end torque drop. Don't worry, even if you lose a little off the line, you will notice a difference around 3000 rpm's.

 

Around 3500 RPMS it looses power. When the car is cold, it hesitates. He says that there is no power. We will take the intake off, and see how it is stock.

 

Your in Chicago? I'm sure its still cold up there!!!. You DO NOT want to have a CAI in your car during winter!! THe car will run like crap in the cold air. It draws in too much cold air for the motor. Trust me I've been through it..When I had my Prelude my mechanic ripped out my CAI and said don't use this crap in winter. So honestly it may just be a weather factor. Take it off, wait until the weather is warmer.

 

take it off, take it off, take it off....

 

It’s the cold weather for sure. When I lived in Ottawa, Canada I experienced exactly the same problem in the winter.

 

hmm. It's been awfully cold in CT over the winter with temps at night dropping into the negatives. It's probably not as cold those of you in Canada but my car with a Berk intake hasn't suffered from the air being "too cold". If anything the car has more pull than it did with warmer weather.

 

We took the intake off and installed the stock one back on. Its a little better, but not close to what it was like before. I think the MAF is messed up.

 

That's why ur friend should be more careful shopping ebay for performance parts. gotta do things right or u run into problems...

 

i think the problem might actually be wid the ecu--seems to me like the ecu went into "learning mode"-- where it pretty much cuts of ALOT of power to get adjusted to any huge mechanical changes to the car (like intakes, fo example). After a while (prolly at least a hundred miles) it should allow power back to the engine, but theres prolly a way to bypass this mode of the ecu.

could also be a MAF problem, but before dishin out some major cash fo a new one, id just make sure its not just an ecu thing...

but since you did specifically say that it loses mad power at 3500 rpm, id say its most likely learning mode of the ecu.

 

Get the Berk from Bryan here on the boards. I ordered one from him but didn't get a chance to install it yet. Shipping is fast and he will guide you on the install. Will try to do mine this coming month or so..when the weather gets a tad warmer.

 

does the berk intake run through the fender? also how much are they?

 

No, its a short RAM set-up... PM Cobymoby for prices...

 

where can I find a berk intake?

 

Or http://www.berktechnology.com/ that can be found using Google and typing in search words "berk intake maxima"...

 

I got mine used from another Org member, but you can buy them new online directly from Berk at www.berktechnology.com.
