I installed a weapon r secret intake about a month ago, it ran fine, but now it seems like from idle to about 4,000 rpm it is really sluggish, then around 4,100 or so the car comes back to life. what should i do it is kinda making me upset i caused me to lose to a darn cavalier. does anyone have any suggestions or have been through this before? thanks for you help

 

check ur MAF sensor, neva happend to me but thats were id check first

 

That is what i was thinking i might do that and reset the ecu even though i did that when i installed the intake
thanks for the thoughts

 

check the intake for leaks. make sure the sleeves are seated properly and tight as possible. check your filter if its not clogged up or unusually dirty.

 

Moved to PH...

 

try cleaning the filter? hehe... it may be super dirty...

 

how could a filter get that dirty in a month?

 

sorry, just throwing around ideas

 

where is the MAF sensor located?

 

the MAF is located on the top, the car kinda seems like it is retarding the timing, now that i think about it

 

on the top of what?

 

It's the sensor that is in the intake's tubing. If it's leaking, it'll throw your A/F mixture off.

 

thanks for the clarification. i put oil around the rubber ring before i stuck it back into the intake.

 

Didin't I read a thread the other day about someones MAF getting trashed by oil from the filter, maybe your addition of oil has had the same effect.

Although you'd be getting a CEL, I think.

 

yea, my MAF went bad after 2000miles. The dealership said that it was the oil from filter. They warrentied the sensor. Ive left the intake on. If it happens again, then that will confirm that the intake is the direct cause of the problem. Im a little skeptic of anything the dealership tells me. However, other people have confirmed that the oil/maf problem is something that has come up with aftermarker intakes in the past. So, its not some random problem that the dealership made up to try to put the blame on me. Hopefully, someone from weapon r will read this and beable to give us a heads up on if they have encountered this problem. Ive talked to Creative Compacts and they stated that they did not have any problems with the intake

 

We haven't had any problems to date with oil from the filter killing MAF's. Our filters come lightly oiled from the factory, not enough to be spread onto a MAF. The only incidents of dead MAFs from an intake I have seen is due to oil from the PCV connection. Our PCV connection is a good length downstream of the MAF, so I don't see that becoming an issue.

I would check all your connections on the intake, including the PCV hose. Reset your ECU, and make sure that the MAF is in and sitting correctly. DO NOT OIL THE O-RING. Any oil allowed to spread around the MAF can kill it in a very short time.

 

how much does a new MAF cost?

 

well, MAF sensors are expensive like $150. the install should be cheap. However, the dealership told me that if it happened agian it would cost me $380

 

ok, so don't oil the O ring? the Injen installation recommended oiling the O ring. i guess i should take my sensor out and wipe any remaining oil off. i just order the weapon r intake because it looks like it was actually designed for the scion and fits much better.

 

wait so were we supposed to oil the WR filter, because i never did. I just put it on and never even thought about having to put oil in it. I thought only cotton filters needed oil, like the K&N and injen
