Well my box started sputtering and the indicator lights all came on so I brought it to the shop. They replaced my O2 sensor and said it was good to go. Well, I pull out of the shop and mabe get a mile down the road when it begins having the same problems. I call the service department ____ed and say they didn't fix anything, the guy comes back at me saying it's my intake. He says in order for him to even look at it I have to put my stock airbox back on, because he never sees Scions with "high performance modifications, it's like trying to find a needle in a hay stack". So I put the stock airbox on and bring it back, all he did was reset the computer and it's running fine now. I still have the stock airbox on, but I would like to put my intake back on. I'm just worried the problem is going to come back. Has anyone ever had this problem, I would appreciate some input from you guys. Thanks.

 

You made sure that the maf sensor was seated properly? The intake was clean on the inside? The coupler was properly sealed along the throttle body?

 

Yeah it was spotless, the maf sensor was on properly. I'm going to put it back on and make sure it has a good seal on the tb. I did recently take it off to clean the filter, so mabe it wasn't sealed well. I've had the intake for over a year with no problems.

 

idt they make those intakes amymore... prob for a reason :shrugs:

 

While it's off, inspect the coupler for any cracks or splits too...
Same with the vent hose.

 

Cool I'm going to check it out this afternoon, thanks for the help.

 

No problem... let me know if it works out.

 

i had the same problem with a no name ebay intake it seemed to be the pipe diameter was slightly larger than the maf sensor was able to read properly ... whne i got my injen intake i pulled the fuse to reset the computer and its been fine ever since

 

yeap all about intake piping diameter at the area of the maf.
