2002 GS300 Won't Start After Installing Weapon*R Intake
 

Help everyone! After I installed Weapon*R intake, my car won't start. I checked all the connection and everything is connected where they're suppose to be. I even disconnected the battery to reset the computer system and the car still won't start. Of course, I reconnected the battery. The car start up fine after I reinstall the factory intake. Any advice would be appreciated.

did you install the MAF backwards? turn it around and try again.

Yeah, that's the mistake that most people would have. :) Did it fix your problem?

Thanks guys! The car starts now. This morning when I start up the GS stalled. It seem like it didn't get enough air. The engine was choking, shaking and then stall. Do I have to adjust anything? If so, what?

The GS lag between 700-1500rpm. It seem like it doesn't want to move. Any advice is appreciated.

make sure the vaccum lines are hooked up right, and then re-reset the ECU and if it still happens re-post.

I rechecked the vaccum hoses and it's connected correctly. I did reset the ECU. It's still lag.

How about giving WR Tech department a call? :)

one of three things:

<> everything not sealed tight... ( rubber gasket inbetween intake and sensor)
<> ECU reset for 20-30 mins then drive for 5-10 mins... it should be ok after that.
<> something wrong with the speed sensor ( dunno what though ... when i had this issue ... thats what the problem was .... thats what the lexus shop said @ least)

It could be the wrong pipe...I got a bad one and had to send it in....is the air diffusser on the side closest the throttle body or the filter?

Thank you everyone for your advice. The sensor holes was welding backward and the MAF sensor was linking air. I'm sending it to Weapon*R and they'll send me another pipe. Once again thank you for all of your advice.

To reset the ECU all I have to do is disconnect the battery for 20 to 30 mins. Is that correct? The reason I ask is because I don't know much about cars. I just drive them.

disconnect the negitive

sorry about your bad experiance with WR intake.
