Finished intake and BIG PROBLEM. HELP?

Finished intake and BIG PROBLEM. HELP?
Well I installed my Berk w/ APEXI, and cleaned my Throttle Body.
The intake sounds great But I have no power now.
If I slowly accelerate it will shift through all gears. ( automatic ). But If I stomp on it from a dead stop She chokes out @ 3500 rpm's. If I am rolling at low speeds and get on it it's like I'm in mud.
I read some where that I have to leave the negative off the batt. overnight so I'm gonna try that.
Do you have any suggestions.
Thanks for all your help. Mike

I was super carefull with it. And yes I plugged it back in.
Also attached to my MAF harness is a small black round thing with a house on it and a light blue plug connector.
All are attached and in good visable condition.

Elaborate on this please! The MAF just plugs in and I don't recal anything being round, but very oval and it's black.

If you have a 2000 then most likely (probably 100%) you've blown your MAF. I did when I installed my Berk w/Apexi and I got a new one installed for under $150 and it's a lot stronger than the first.
They really should do something about the 2000 MAF.

About 2 inches from th MAF sensor plug the caple splits. and2 wire go to a black sensor thing. It looks like a bottle cap sort of. but a little bigger. it is connected to the cable by a blue plug. It has a smmal dia. hose attached too it runs down by the 2 hoses that where routed by th stock box.
I have a 2000 w/ Cali- Emmisions.

If your asking me if I have the MAF tube facing the right way. I think it can only go one way. one end has a flange on it and it goes to the filter.

Go to Cardomain.com and startup a page, it's the easiest way.
You know you have your MAF attached correctly if the arrow on it is pointing toward the TB and the screen is infront of the sensor, so it is screening the air prior to the sensor.

Isn't the MAF covered by the emissions warranty? Put your stock airbox back in and go get a new one from the dealership....
I have yet to drive my car... disconnected the battery and letting it sit for 24 hours.... I'll let ya know how it goes when I get the chance and also whether I blow mine too or not.... all the best....

if your car doesnt go past 3500 rpm's, when MAF blows, the car goes into limp mode.. basically still allowing you to drive. but u cant punch it no more..
btw, did u get a SES light? go to autozone if u can .. see if they can pull any codes from the ECU, that might help.

Yeah, it is the sensor. I disconnected my entire intake and cleaned it with a carborator cleaner while gasing, my rpms wouldent go higher than 3.5k on a cali emission maxima gxe.
The sensor gets blown too easy.

I went down to my Nissan dealer and picked up a MAF. It was $90.00 and it's the whole thing hosing and all.
....Enclosed was a letter stating...
"This unit requires special ECM reprograming of the vehicle.
Refer to TSB NTB01-036/ITB01-029 for the special ECM ID code that must be entered in the ASIST ECM Data screen to download the correct data.
This data is not available through the regular MY/Model lookup."
Should I take it in for programing?
Should I put the stock intake and new MAF on and than bring it in?
Should I put the new one on w/ the Berk and bring it in since I have 62K on my car and am out of warraty anyway?
I have not gotten the SES light yet
What is the code for it though so if I call nissan in Monday I can say I got it over the weekend and picked up the part.
Thanks, Mike

Thats a good question and I have asked it myself, but have never gotten a clear answer. I, and others, have installed the "updated" MAF ourselves and have not had the ECU reprogramed/updated. I installed a new MAF 6 months ago without updating the ECU when I installed my Berk. So far,nothing unusual has happened.
We need to find out what the reprogramming of the ECU does and why it is needed. Does anyone know? All I can tell you is that I did not update my ECU and everything seems normal.

If this is true I'll check it out when it stops raining here in NJ.
If it is the MAF is it safe ot install and drive for a few days prior to ECU flash?

Well then your suggestion of me being "wrong" only applies part of the time. If you have a late build 2001 then you have the updated, right? I know that my new one is updated. Regardless, if you have the week one and you plan on doing any mods, especially intake, then you should consider getting the upgrade and/or expecting your MAF to blow.

Well It's Sunday and Ivan has blown through. The sun is shining and all is well in my little MAX world. I put my new MAF on and it's a new car again. It seems like my low end throttle response is back to what it was like a while ago. I was having some cold start acceleertaion problems for about a month. Thats gone too.
Now all I want to know is what will the ECU flash do , how much is it, and is it worht it.
Thanks for everyones help. Mike

The main symptom is loss of high RPM power.
